Starting From Scratch With Indoor Pool

by Anna Gagliardi
(Niagara Falls, ON, Canada)

Want to add and an enclosed, underground pool to my existing house. I live in a climate where I have 4 seasons. I want a pool that I can enjoy all year round, not just in the summer. What kind of cost am I expecting? Is this practical or am I setting myself up for complications?

I don't have images to show you but this is what I envision my pool area to look like:

1. Solarium style ceiling
2. Walls are both windows and brick.
3. Screened Patio door(s) to open in the summer.

Thanks for the question Anna

Yes you can have an indoor pool. Many people do with much success. Pretty much, if you have the money you can do almost anything you want. But I'll assume you're on a budget and like to keep costs to a minimum while having a great pool.

The cost can vary from house to house. There are so many variables that it would be difficult to name all of them, but here are some things to consider.

A solarium style is very similar to a normal "sun room" but with some variations. sometimes it can mean the same thing but used in different parts of the world.

Whenever anyone is undertaking an indoor pool project I always tell them the four big things are:

- Heat source
- Fresh air ducts
- Exhaust
- Ventilation

Having glass walls or ceilings will mean more heat loss, so be sure to take that into account.

You need a good supply of fresh air. If you don't have this the room will become stagnant and moist very quickly due to evaporation. This leads to wet floors, walls and ceilings. In turn, this leads to mold and bacteria.

Then you need to vent and
exhaust the area. Get rid of the old air and bring in new. this will also keep the combined chlorine (CC) or chlormaines down in the pool. If you've ever been to an indoor pool and smelled the "chlorine smell" that's what it is, the chloramines in the pool and the air.

Use a vapor barrier. This barrier is installed in the wall surrounding your pool to keep the moisture and vapors from the rest of your home. Also consider moisture-proof insulation in the walls.

Obviously you take the risk of underground leaks with an inground pool. This can be costly and the leak detection company may need to break up your house flooring in order to fix the leak.

Most indoor pools will be heated, so take this into account as well. Even though you may have a screen door or porch, and warm air going into the pool area, it may not be enough to adequately heat the pool. For heaters, you have a choice of gas, electric, or solar.

Depending on what you want, the range can be anywhere from $15,000 up to $50,000. There's the excavation, any underground water pipes or electrical wires, vinyl, concrete or fiberglass pools, zoning regulations, building permits, and sewer lines to name just a few.

An inground pool, regardless of whether it's an outdoor or indoor pool, is a major undertaking and needs to be carefully considered. Do your due diligence and homework. You'll make the right decision.

Info. About How To Build An Indoor Pool

by Tim
(Seguin, TX)

Was trying to figure out where to start on finding someone to build an indoor pool. Our house would lend itself to build out from the front. Do not know what type of structure to go with. Cost is an issue. Will standard type construction with multiple french doors work.

Was concerned about humidity. Would plan on separate hvac system. Do you have any contacts in Central Texas? Articles on internet are very limited as well as contractors that do vs outdoor pools.

Thanks for the questions Tim

You asked about the type of structure so I will assume you mean fiberglass, concrete, etc...

This really depends on your personal preference. Being that I don't sell either one I can give you an unbiased opinion. A concrete/plaster pool is good and will hold up for years. You can get pretty much any shape you want and normally costs less than a fiberglass or pebble tec pool. They do use more chemicals.

I will assume in Texas you have hard water so keeping the calcium hardness down might be an issue. Fiberglass pool are great and use less chemicals but you're limited as to the shapes. I'm not saying on two shapes, but having one custom made might be difficult.

A good but sometimes overlooked kind of pool is pebble tec. I think it rates between a concrete and fiberglass. You can get any shape you want and they're pretty good on chemicals.

I took care of many pebble tec pools for years when I maintained pools in Arizona and I like them. For cost you're probably going to start out around $20,000 and work up from there.

Humidity is a big factor and you can find lots of information on that in the indoor pool page link above. I take care of the YMCA indoor pool (80,000 gallons) so I have first hand knowledge about the importance of heating, humidity, exhaust, and fresh air flow of an indoor pool.

Unfortunately I have no contact with any contractors in Texas. In my opinion, the most important factor between an indoor pool vs. an outdoor pool is the exhaust and fresh air flow.

If you don't have them the humidity will rapidly rise in the room causing mold, mildew, and the moist air will find itself into the walls, ceiling and attic of the house causing more problems down the road. We replaced all the roof tiles in the pool room at the Y because of this very issue. Rust, water damage, and mold because the system went down.

Hope this helps and good luck with the pool. I'd love to see before and after pictures if you get a chance.

Heating Screened In Pool

My screen blocks some of the heat from the sun, plus the pool is on the East side of the house.

What is the best and most economical way to heat my pool?

Thanks for the question

First I'd like to direct your attention to this page. It has alot of good information on it and might answer some of your questions:

Pool Question..Indoor Heater

Concerning heating your pool, I've had much luck with gas or electric heaters. However, it depends on where you live relative to the cost of electric and gas. If you don't have gas outlets or access to it, or propane, you probably need to go with electric. This has the faster recovery time than a solar pool heater or gas. Heat pumps use electricity and electric rates will continue to rise.

Gas heaters burn either propane or natural gas. Unfortunately the cost of propane and natural gas has gone up during the last 10 years. That being said, you may want to have a gas heater only as a back-up to either a solar or electric heater.

Solar heaters have come along way in the last few years and can give you years of service.

Solar pool heating is the most cost-effective and cleanest way to heat your pool. Hope this helps make your decision easier.

Pool Enclosure/Remodeling/Heating

by Jim

We Live in Mount Dora, have an older pool/screen room that needs help. I would like totally enclosed, but that may not be reasonable. I wish pool, 6.5 feet deep to be more usable throughout year. Solar is prpbably not an option, trees, etc. Would like a consultation, ideas. Do you live in Orlando? Would you be interested in an on site consultation? Fee?



Thanks for the question Jim

Sorry but I don't live near Orlando. Due to the nature of the issue it would be best for someone to see where the area is. Remodeling and pool enclosures are a little out of the scope of my expertise. I didn't have any on my pool route. I helped out with a couple of issues when I lived in Oregon but that's about it.

Good luck with your pool.

by Gary Lalman
(Payson, Az )

We are planning a build in Star Valley, Az and want to put a 15 to 20 foot pool in the house or cover a pool outside to use year around.. from what we can tell we want fiberglass and something besides chlorine.

We are having to do this for health reasons not for image in the community due to my wife's health issues.
