A pool house costs $40,000 to $200,000 in DFW. An open cabana with a covered seating area and storage runs $40,000 to $80,000. Adding a full bathroom and changing area runs $90,000 to $140,000. A conditioned pool house with a kitchenette and guest space runs $150,000 to $200,000 and above.
Four levels, four very different buildings
| Type | Typical Cost | What It Includes |
|---|---|---|
| Open cabana | $40,000–$80,000 | Covered structure, seating, storage, fans, lighting |
| Cabana with half bath | $70,000–$110,000 | Above plus a plumbed half bath and outdoor shower |
| Pool house with full bath | $90,000–$140,000 | Enclosed changing space, full bath, storage, equipment room |
| Conditioned pool house / guest space | $150,000–$200,000+ | Full HVAC, kitchenette, sleeping area — effectively a casita |
The jump from cabana to pool house is the bathroom. Once plumbing runs out there, the structure needs a foundation designed for it, a drain tied to the sanitary system, venting, and freeze protection — which is the same threshold that separates a covered patio from a small building.
The bathroom is the point
Almost everyone who builds a pool house says the same thing afterward: the bathroom is what changed how the pool gets used. It keeps wet feet and wet swimsuits out of the house entirely, which in a house with nice floors is worth more than any other feature out there.
An outdoor shower next to it is the second-best value — cheap to add while the plumbing is already being run, and it keeps chlorine and sunscreen out of the pool and out of the house.
What else earns its space
Equipment storage for the pool vacuum, floats, chemicals, and furniture cushions. This is the unglamorous feature that eliminates the clutter every pool otherwise accumulates.
A pool equipment room that hides and quiets the pump and filter, which are otherwise a visual and noise problem.
Ceiling fans, which in Texas are what make a shaded structure usable rather than just shaded.
A refrigerator and counter, so nobody walks into the house dripping to get a drink.
A changing area with hooks and a bench — simple, and it prevents the bathroom becoming a bottleneck.
Design and code notes
Match the house. A pool house that echoes the main home’s roof pitch, materials, and window proportions reads as part of the property. One that does not looks like a shed by the pool, and it hurts rather than helps at resale.
Practical requirements: it needs an engineered foundation like any structure, setbacks and lot coverage apply, pool barrier requirements may govern how a doorway from the structure to the pool area is treated, and freeze protection for any plumbing is genuinely necessary in North Texas — an outdoor shower that cannot drain down splits a pipe in January.
If it includes a kitchen and sleeping space, most cities will treat it as an accessory dwelling unit with the zoning that implies.
Frequently Asked Questions
Do you need a permit for a pool house?
Yes. It is a structure, so building permits, setbacks, and lot coverage limits apply, plus electrical, plumbing, and mechanical permits for anything wired, plumbed, or conditioned. Pool barrier requirements may also affect the design.
Is a pool house worth it?
If the pool gets regular use, the bathroom alone changes how the whole backyard functions by keeping wet swimmers out of the house. As a resale feature it appeals to the same buyers who want the pool.
What is the difference between a cabana and a pool house?
A cabana is typically an open covered structure for shade, seating, and storage. A pool house is enclosed with at least a bathroom and changing space, and often conditioned living area.
Can a pool house be used as a guest house?
Yes, if it is conditioned and includes a full bathroom and sleeping space. Adding a kitchen usually makes it an accessory dwelling unit for zoning purposes, which brings city and HOA rules into play.
How do you protect pool house plumbing from freezing?
The plumbing has to be designed to drain down, with a shutoff inside the conditioned envelope and appropriate slope. North Texas hard freezes are real, and retrofitting freeze protection after a split pipe is far more expensive.
