Hydrofloors, The Hidden Pool Feature Homeowners Love



Hydrofloors are the Hidden Pool Feature Homeowners Love

One of the coolest inground pool features these days that has taken social media by storm are Hydrofloors. These incredible movable pool floor systems enable you to achieve the ultimate hidden pool. Hydrofloors were first introduced to the pool industry back in 2007. Since then they have slowly been gaining traction with builders and homeowners alike.

Movable pool floors have been around for decades. If you’ve ever seen the pool from ‘It’s Wonderful Life’, you’d recall a memorable scene involving a dance floor opening up to a swimming pool. Technology has certainly come a long way since George Bailey took the plunge. These movable floors vertically rise to fill in the pool area with usable space within minutes.

What are Hydrofloors? Twinscape Group is the visionary behind these incredible movable pool floor systems.

What Are Hydrofloors?

Twinscape Group is the pioneer behind this revolutionary technology that is enabling homeowners to reenvision their pool area as a dual-purpose space. It is now possible to go from an indoor gym to an indoor pool in an instant using Hydrofloors. The movable swimming pool floors can be lowered to varying depths. It can also be elevated to ground level to be utilized as a flat-top surface.

The James Bondesque pool feature isn’t just becoming more popular with luxury homeowners. Hydrofloors are also becoming a big hit with aquatic centers. The ability to raise and lower the pool floor makes it possible to hold infant swim classes at 10 am, an adult lap swim at noon, and a swim meet competition at 3pm all in the same pool.

Transforming the pool to different depths happens all by pressing a single button. Hydrofloors also have applications for creating better therapy pools. Slip-resistant, movable pool floor systems can be easily adjusted. This allows swimmers of any physical condition to enter and exit the pool with greater ease. Hydrofloors eliminate the need for slings, hoists, and access ramps.

Movable Pool Floors Are Attracting More Pool Builders

Builders like Paolo Benedetti of Aquatic Technology out of Morgan Hill, CA, have become a big fan of Hydrofloors. They enjoy the ability to do multiple depth floor systems that can accommodate popular finishes (i.e., tile, glass-mosaic, and even marble). That is accompanied by Hydrofloors’ enormous load capacity. Hydrofloors surpass a home’s conventional floor strength rating of 55 lb/ft when lifted.

Benedetti recently shared one of the most recent projects he collaborated on with Panorama Pool Builders of White Fish, MT. This incredible over the top luxury inground pool exemplifies what can be achieved in the backyard with Hydrofloor movable pool floor systems.

What is also remarkable is that a Hydrofloor pool is a 100% safe pool cover that can convert into a usable patio space within minutes. This provides the versatility to create unique pool environments that are multiuse spaces. That is perhaps the most appealing aspect for pool builders.

How Do Hydrofloors Work?

A series of cables and a pulley system with a water-based hydraulic cylinder comprise much of the technology behind Hydrofloors. Locking pins that automatically slide in the pool shell walls help achieve an incredibly high load capacity (250 kg/m2). Buoyancy packs are installed underneath the structure, which floats the pool floor to the surface. The floor is pulled down with a cable and pulley system with water-based hydraulic cylinder to the desired depth. Water passes slowly enough so that the water percolates above the floor to quickly drain away from a small gap around the perimeter.

Separating The Fantasy of Movable Pool Floors From Reality

There have been plenty of moving pool floor system videos being shared on social media lately. Some of these time-lapse videos are incredibly entertaining to watch. Quite a few of them show pool floors that disappear within seconds. Realistically you’re looking at around 8-10 minutes for a complete transformation from patio to pool.

Let’s also set realistic expectations about market penetration on these systems. While the videos are becoming popular on social media, and homeowners might be wondering if they can have one of their own; this is still a pool feature reserved for the elite. The movable pool floor system alone can cost hundreds of thousands of dollars; which can be pricey – even in terms of luxury inground pools.

How Much Does a Hydrofloor Pool Cost?

Each square foot of the movable floor system can cost anywhere from $300 to $550. This makes movable pool floors a unique but very expensive pool feature. Construction costs considered, a hidden pool with a Hydrofloor can cost millions, according to Alan Crownover of Paradise Pools and Garden. Crownover is a San Francisco-area pool builder, who’s designed at least one Hydrofloor pool so far. He said the starting price for similar projects would run someone about $2 million.

Crownover is working on another exciting Hydrofloor project. This one involves a private yacht that wants to land a helicopter on the roof. He is planning a dual-purpose landing pad/pool. The owner will be able to convert into a swimming pool and back again whenever guests drop in. Truly a unique project that we can’t wait to see get off the ground (no pun intended).

Luxury Pool Feature With a High Price Tag

The high cost associated with this particular pool feature puts it out of reach for all but the most affluent homeowners. Real estate agents have reported an uptick of homes with hidden pools hitting the market in recent years. However, this doesn’t indicate they’ve become more affordable yet. Most regular inground pools typically start at around $50,000. The starting price for a Hydrofloor is $230,000. This makes this a unique pool feature that you’ll still find in only a finite amount of residential homes.

A movable pool floor system such as this is a luxury pool feature that can exceed several million dollars.

Twinscape Group is definitely setting the bar in movable pool floors when it comes to finding exciting and innovative new ways to conceal a swimming pool. They are also pushing the envelope with movable benches, pool covers, and submersible walls and bridges.

Inexpensive Hidden Pool Projects

Want a hidden pool but can’t afford a Hydrofloor system? You might want to try the DIY approach. You can try and build your own. Gil Klar, an Israeli electrical engineer, spent three months and around $10,000 building his own hidden pool. One that is quite similar to the sliding dance floor shown in “It’s a Wonderful Life”.

No Deck Needed

Pool Design For Your Outdoor Living Environment

Pool Design For Your Outdoor Living Environment
50 of 50

Cameron Rhodes, the lead designer and co-owner of Southern Poolscapes has been designing high-end outdoor living environments for the better part of a decade. When it comes to selecting a pool design, Rhodes said “It’s important to meet with a pool builder that understands your vision for the space. Many times, it takes a while to help homeowners articulate that into a design plan that accurately represents what their dream is.”

As one of the leading luxury pool builders in the South, Rhodes has his fingers on the pulse of what pool design features homeowners want in their inground pool. “Moving water is extremely popular,” said Rhodes, “There is something truly serene about coming into the backyard and hearing the sound of a waterfall or sheer descent running. That ambient sound is very peaceful and adds to the overall atmosphere and ambiance in a high-end custom pool.”

In terms of what luxury homeowners are adding to their pools, Rhodes replied, “We’ve seen more and more homeowners requesting massive tanning ledges. Many of these folks have a family with small children and these ledges provide a larger shallow area to enjoy time in the pool with younger more inexperienced swimmers. Plus when coupled with a set of ledge loungers, the effect is pretty impressive,” said Rhodes. 

“We are also seeing more homeowners looking for a cleaner more refined look to their inground pool,” said Rhodes, “We’re doing a lot of perimeter overflow projects where you get that seamless sheet of glass look when the waterline is flush with the coping.” 

As far as outdoor living amenities go, Rhodes says that homeowners are going all out on high-end materials, despite the rising costs that we’ve seen across the board this season.

“By and large people want a beautiful outdoor living environment,” said Rhodes, “we’re seeing more customers add on Pavilions, outdoor kitchens, firepits, and go all out on their landscaping. It goes to show their mindset; that if they’re stuck at home, they are going to make sure that their home is definitely someplace that they want to be.”

Hot Tubs

Hot Tub Party Bus Ordered To Shut Down



Hot Tub Party Bus Forced To Shut Down Due to Lack of Permit

The owner of one of Nashville’s famous and popular party buses, Music City Party Tub, has been ordered to stop operating a public pool without a permit, according to a complaint. The business has been operating as an alternative to traditional party buses and limo rental services.

The Tennessean reported that in a lawsuit filed last week, the Metropolitan Government of Nashville requested that the mobile tub be temporarily shut down. Next Wednesday is the date of their hearing.

Popular Hot Tub Party Bus Operating Since 2019

According to the complaint, health regulators sent a notice to Music City Party Tub on August 11 informing them of the infraction. For the past few years the party bus has been a regular sight in Nashville’s entertainment sector, boasting that it can accommodate hot tub parties of up to six or seven people at a time.

Hot Tub Party Bus Ordered To Shut Down
Officials ordered the popular Nashville party bus to shut down due to a lack of proper permitting.

The health department claims Guy Williams visited in that month and was urged by regulators to submit pool design plans and apply for a swimming pool permit, which he did. When the trailer-mounted party tub was inspected, the inspectors told Williams a number of items needed to be fixed before it could be authorized. However, according to the lawsuit, he never returned.

The suit claims that in September 2020, health department employees saw Williams driving the party busy again and asked him about not having a pool permit. He claimed he was excluded since his hot tub lacked the “minimum volume” of a public pool by 50 gallons (190 liters).

According to the lawsuit, such exceptions do not exist. The business also has not registered with the state and has no business license, according to the complaint.

Diagnosing a Pool Leak Isn’t Always So Cut & Dry

Think you may have a pool leak? Finding the source can be a challenge.



Diagnosing a Pool Leak

Diagnosing a pool leak can put some pool owners in over their head – it’s a fact. No matter what type of pool you own, every swimming pool naturally loses some water due to evaporation, splash-out and backwashing. However, when you find yourself watering your pool way too often, it’s cause to stop and think. If you find yourself routinely adding more than two inches of water to your pool, you may just have a pool leak, according to experts.

A pool leak is a very common problem but does require some time and effort to diagnose properly. Swimming pools are designed to be waterproof, but sealants can and do deteriorate over time. Components inside of your pool can shift, settle, or just plain wear out. It’s not uncommon for older swimming pools to have multiple leaks in multiple locations.

Early Pool Leak Detection Can Prevent Costly Repairs

Pools can leak through any of the fittings, equipment, plumbing, or even the pool shell itself. Neglecting to fix a pool leak can cause incredible damage in both inground and above ground pools. Pool leaks are serious business and can actually compromise the sub structure of the pool itself. It’s not common for a leak to systematically wash away the backfill which supports the pool walls and deck.

Diagnosing a Pool Leak is a Specialty Service for Pool Contractors

The process of identifying and diagnosing pool leaks come and how to fix them is a highly specialized area in the pool industry. While many pool service technicians may specialize in cleaning and maintaining pools, only a portion actually specialize in leak detection. You need specialized equipment and training to properly perform a leak inspection.

Pool Leaks Can Cost Homeowners Thousands

A pool leak can ultimately result in a slew of bills and repairs if not addressed quickly. One thing homeowners notice right away is a surge in their water or electric bill. Rising utility costs could suggest the need for a repair elsewhere in your home, but your pool should be towards the top of your list of things to look into. If you do have a pool leak, the surge should be obvious and significantly higher than the general spike in utility costs seen throughout pool season.

Just to put things in perspective, a pinhole leak can waste up to 970 gallons of water each and ever day. In terms of water consumption that is roughly four times the amount of water that an average family consumes each day.

DIY Pool Leak Detection Methods

Bucket Method

If your swimming pool, spa, or fountain is losing half an inch of water each day, it could be due to evaporation or it very well could be a leak. Evaporation and splash out is the most likely cause of a quarter-inch to a half inch of water loss each day. Any more than that, and you may want to do the bucket test to make sure you don’t have a leak.

Leak Detection – Bucket Test

  • First, start off by filling your swimming pool to it’s standard level.
  • Next, fill a 5 gallon bucket with water up to 1 inch from the top.
  • Submerge the bucket in the pool to a depth of about 5 inches, place it on the first or second step of the swimming pool.
  • Mark the water level inside of the bucket with a magic marker as well as the water level outside the bucket.
  • Return in 24 hours to compare the inside to the outside water level. If the water level outside of the bucket has substantially dropped more than the water level inside the bucket, it’s quite possible you could have a pool leak.

Dye Method

Using the dye method will involve using a pool leak detection kit. This method is really only effective if you have a pretty good idea of the general vicinity where the leak may be.

To perform this test, all you do is squirt the dye close to where you suspect the leak is. If the leak is there, you should notice the dye being sucked through the source of the leak. This test may require being underwater for some time. You may want to use a pair of goggles to see better. You’ll also have to stay pretty still so as not to disrupt the dye during the test.

The most common pool leak usually occurs in the skimmer

8 Questions To Ask If You Think You Have a Pool Leak

appears to be a crack, put some pool leak test dye near it while the pump is turned off and the water is still running to check if the dye gets sucked into the crack. Underwater lights can and do leak as well. One of the most common leaks occur around the conduit that connects the light niche to the junction box.

Is the soil around the pool area damp all the time?

Do a thorough inspection of the perimeter around the pool deck and between the pool and the equipment pad. Examine the ground for moist soil and deterioration. If your pool slopes down hill, stroll around to see if there is any water weeping down the hillside.

Is the shell leaking?

Some sources of leaks are the result of structural design flaws. These types of pool leaks are the most serious type of leak and most expensive to repair. Leaks can cause settling of the pool shell. A leak can create conditions for unpredictable ground movement that is likely to produce cracks in the walls, floor, or both. In concrete pools – high slump concrete, low cement content, or poor craftsmanship and curing are all likely to generate low quality concrete that allows water to travel right through it. Thermal or shrinkage stress cracks can occur. Cold joints or weak construction joints can create leaks as well. Improperly sealed joints can create conditions for structural pool leaks as well.

Is the skimmer leaking?

The most common pool leak usually occurs in the skimmer throat at some point. The skimmer does has a tendency to move somewhat when the pool and deck expand and contract. This movement can break the sealant between the pool wall and the skimmer over time. The skimmer can be dye tested (with the pump turned off) to see if there is a leak pulling water into the cracks surrounding the skimmer opening.

Is the pool leak coming from underground plumbing?

Honestly, it’s very rare that a pool leak is going to happen in the subsurface plumbing. That’s not to say that it doesn’t happen though. From time to time a leak can occur at a pipe junction beneath the pool deck or beneath the skimmer. These types of repairs rarely necessitate having to hire a team of pool builders to dig up the entire backyard in order to find the source. The simplest approach to check if the pipes are leaking is to turn off the pump and stop all of the lines. If it continues to leak, it’s probably not the pipes. If the leaking does stop, the plugs can be removed separately to determine if the leaking resumes, though some pools only leak when the pump is running. Once a complete leak inspection has been performed, a pool plumbing pressure test on the pipes themselves can be conducted to determine if any are leaking.

If there is an underground leak, in 90% of cases a very small 3’x3′ hole in the deck can be cut to fix the break, but it’s rarely ever necessary to replace a complete run of pipe.

Is the pool leaking when the pool equipment is running?

If you find that the pool is leaking when the equipment is running, this could be a very good indication that there is a pressure-side return leak. The piping on the pressure side (after the pump) is under pressure when the filter pump is turned on. This can cause little drips to turn into spraying gushers. Checking the waste or backwash line for water that is constantly flowing can tell you if you have a leak.

One inch of pool water is equal to 500 gallons. Look for weepers where subsurface leaking is trickling downhill from the pool. Examine the yard for soft or moist places, particularly on the pool’s side where the plumbing returns water to the pool.

Does the pool leak when the pool equipment is turned off?

If the pool is leaking when the equipment is completely turned off this usually implies a suction-side leak or a problem with the plumbing itself. When the pump is turned on, air can be brought in via voids that would otherwise leak. If you have a clear lid, you usually see air bubbles in the pump basket. You’ll also observe air bubbling out of the return lines, or air repeatedly building up inside the filter tank.

Cost for Pool Leak Detection

Testing an average residential pool, including both the plumbing and the structure, typically costs $400-$500. It’s not always necessary to empty the pool in order to diagnose and repair many types of pool leaks. However, expect to pay upwards from $500 if a scuba dive is required in order to properly detect the source of the leak.

Cost of Pool Leak Inspection & Repairs

Labor and materials for most basic leak repairs typically start anywhere from $500 to $1,500, not including the expense of draining and refilling (if needed). If the problem is determined to be coming from the pipes themselves or the structure of the pool, anticipate opening up your wallet for major repair costs. The entire cost of repairing a major structural leak in the shell or in underground plumbing is determined by the severity of the damage, the location of the leak, and the difficulty of the repair work.
