Is it good to construct pools in winter?

I see no problem installing an indoor pool. The pro you choose should advise you. Have you considered an above ground exercise pool? Some a large enough to accommodate several people.

The company you talked to would probably know best, but I'd check with a couple of other companies, just to get different bids and to ask other experts the same questions. It never hurts to ask the same question multiple times to multiple people--you'll learn something new every time.

This is a great concept.

Whatever you do, I would be very cognizant of humidity & condensation and how that can be quite destructive.

I would use a mini split and exhaust fans need to be direct vent to the outside.

Hi Stephanie,

I can speak from experience...we live in Maryland and have an indoor, in-ground pool, it came with the house and they did a beautiful job. Our pool has no drain, I don't know if this is a factor you have considered, but in Boston, the pipes may freeze up if they go to the outside. We have a gas heater and it directly wired to the box.

Another thing we have noticed is we do not use the pool in winter because the ground is cold, the heat from the water goes into the surrounding concrete. ground, and air, heating that up and dropping the water temperature. Keep that in mind even though yours will be indoors, you will spend lots of money just to heat and maintain the water temperature in winter. You spa could be the answer to that, not sure what you have in mind for it.

Humidity is another factor, you will need the proper material so you do not grow black mold on your walls.

What we do is go to the Y during the winter, ours has an Olympic size pool, they offer all kinds of classes well into the evening. My husband also has diabetes and he gets his exercise there doing water weights while I do Aqua Zumba.

Best to you. Any more questions, please ask, we'd be glad to help.

Re-read Stephanie's comment.

Keep in mind that the cost of installing a home pool is only a portion of the real cost of having one. They require constant and diligent maintenance, and no cutting corners on replacing all necessary parts to keep them functioning safely and properly. Your electric or gas bill will go up considerably due to the cost of heating the water, and you will have increased humidity that will need to be addressed properly, which can be costly.

Also check with your home insurance carrier to see if you may need to purchase additional coverage for unexpected leaks, floods, or accidents.

Compare the cost of an annual pass to your local public indoor pool, even including the cost of renting your own private lane, with the cost of one years maintenance, before you jump into this project.

There should be no problem constructing an indoor pool in the winter.

As long as you don't live in an area where the ground freezes in winter, or where it rains a lot they should be able to install one for you. I would call some local pool companies and see what they think.
