Indoor Pool Design and Construction

What an indoor pool really needs

Dehumidification first

Warm water in a closed room will destroy framing and finishes without properly sized air handling. It is the first line item, not the last.

Heating that keeps up

Water and air both need heat in January. We size equipment for the coldest week, not the average one.

Vapor barriers and finishes

Wall assemblies, glazing and surfaces are specified for constant humidity so nothing swells or spots.

Slip-safe surroundings

Interior decking gets a wet-rated finish with real drainage, so the room stays safe and dry underfoot.

Quiet equipment placement

Pumps and blowers go in an isolated space. An indoor pool amplifies every noise you did not plan for.

Coordinated trades

We work alongside your builder and mechanical contractor so the pool and the room are designed as one system.

Planning an indoor pool room

Best case: new construction

Planning the enclosure and the pool together is far less expensive than retrofitting either. Bring us in while the addition is still on paper.

Retrofits are possible

Existing sunrooms and outbuildings can work if the structure, ventilation and drainage can be brought up to spec. We assess honestly before you commit.

Fiberglass or gunite

Both work indoors. Fiberglass installs faster in a tight space; gunite gives you the shape when the room is unusual.

Indoor pool questions

Ask us an indoor pool question

Are indoor pools much more expensive?

The pool costs about the same; the enclosure, air handling and heating are what add up. Budget for the room as its own project.

What goes wrong most often?

Undersized dehumidification. Every serious indoor pool failure we have been called to look at traces back to humidity, not water.

Can I convert an existing room?

Sometimes. It depends on the slab, the structure and whether ventilation can be added. We will tell you if it is not worth it.

How warm should the water be?

Most owners settle in the low eighties, with air a couple of degrees warmer. That balance keeps evaporation manageable.

Do you service indoor pools?

Yes, and it matters more indoors. Weekly maintenance and equipment checks keep small humidity problems from becoming structural ones.

Plan an indoor pool early

The sooner we see the plans, the less the whole project costs. Bring us in at the drawing stage.
