I like the blk and wht but not those horrible dark walls could you maybe post an actul floor plan showing the shape of the pool.

I was in a home that had an interior pool and the smell of chlorine permeated the home, so do some research on keeping the pool clean. No one wants a home that smells like a restroom.

Start putting together photos of indoor pools that you think are inspirational. Can you add skylights over the pool?

Since you have such a large ceiling over the pool I might look to being creative there.

Since the room will have humidity, maybe a Living Wall could be a good addition. Withe proper lighting it could be great at night.

It looks like there is no view from the black and white room and a floor plan really is necessary to see how things relate...but maybe the space would be better used opened to the pool room ?..allowing in the natural light with the fence offering privacy to the pool area...creating a more inviting indoor pool area....using any of the above inspiration pictures for decor....

I highly recommend a de-humidifiaction system such as Desert-Aire. Otherwise everything in that room will rot from too much moisture. Coupled with an HVAC system, the proper exchange of fresh air will prevent the build up of chloramines in the room, which is the powerful chlorine smell associated in indoor pools.

An automatic cover is recommended to keep moisture content down when the pool is not in use.

As Mystic Pools stated above, an automatic cover is an easy (and relatively inexpensive) way to reduce evaporation protecting the structure, while reducing your overall operating costs, and within a number of years, realize a full ROI
