Salon and spa finish-outs sit between an office and a restaurant in cost, because they carry real plumbing and ventilation without a full commercial kitchen. In DFW, 2026 salon, spa, and med-spa finish-outs run roughly $90 to $250 per square foot. A simple cut-and-color salon in a second-generation suite sits low; a med-spa with treatment rooms, wet rooms, and clinical equipment runs to the top.
DFW Salon & Med-Spa Finish-Out Cost (2026)
| Concept | Cost per Sq Ft | Drivers |
|---|---|---|
| Hair salon | $90–$160 | Shampoo bowls, stations, ventilation, finishes |
| Salon suites (rental model) | $110–$200 | Many small rooms, plumbing, separate power |
| Day spa | $120–$220 | Wet rooms, treatment rooms, water heating |
| Med-spa | $140–$250+ | Clinical rooms, equipment power, sometimes med plumbing |
What Drives a Salon or Spa Build-Out Cost
- —Plumbing to shampoo bowls, pedicure spas, and treatment-room sinks
- —Water-heater capacity sized for simultaneous wet stations
- —Ventilation and make-up air for color, nail, and chemical fumes
- —Electrical for dryers, styling stations, and med-spa equipment
- —Treatment-room walls, wet-room finishes, and sound separation
- —ADA restroom and accessibility throughout the floor
Salon Suites Multiply the Rooms - and the Cost
The salon-suite rental model has driven a lot of DFW build-outs, and it is more expensive per square foot than it looks. Instead of one open floor, you are building many small private rooms, each often wanting its own plumbing, power, and sometimes a sink. More walls, more doors, more rough-ins. We lay out suites to balance the rentable room count against what the plumbing and electrical can reasonably serve, so the model pencils out instead of blowing the budget on infrastructure.
Ventilation Is the Detail Most Quotes Miss
Color, acetone, and nail product fumes need real ventilation, and a med-spa adds clinical air requirements on top. It is the item a cheap quote skips and an inspector and your staff both notice. We size the exhaust and make-up air for the actual services you offer, so the space is comfortable to work in and passes inspection rather than getting flagged after you have already moved in.

Permits and Med-Spa Considerations
A standard salon runs through the city building permit; a med-spa offering medical treatments can add health and accessibility requirements closer to a clinical space, depending on the services and who supervises them. We confirm which review path your concept falls under before design, because a med-spa scoped as a salon is the kind of mismatch that surfaces at inspection. Then we submit complete drawings and work the schedule backward from your opening.
What to Confirm Before You Sign a Salon Lease
- —Is there enough water-heater capacity and plumbing for your wet stations?
- —Can the space be ventilated for color, nail, or treatment chemicals?
- —For suites, how many rooms can the plumbing and power realistically serve?
- —For a med-spa, does your service menu trigger clinical review requirements?
- —What does the TI allowance cover, and who carries the permit and certificate of occupancy?

Frequently Asked Questions
Common questions about this topic from DFW homeowners and project planners.
How much does a salon or med-spa finish-out cost in DFW?
In 2026, DFW salon and spa finish-outs run about $90 to $250 per square foot. A hair salon in a second-generation suite is at the low end; salon suites, day spas, and med-spas with treatment rooms and clinical equipment reach the top.
Why are salon suites more expensive per square foot?
Instead of one open floor, you build many small private rooms, each often wanting its own plumbing, power, and a sink. More walls, doors, and rough-ins push the per-square-foot cost above an open salon, so the rentable room count has to be balanced against what the infrastructure can serve.
What do cheap salon build-out quotes usually leave out?
Ventilation. Color, acetone, and nail fumes - and a med-spa's clinical air needs - require real exhaust and make-up air. A low quote that skips it gets flagged at inspection and makes the space uncomfortable to work in. We size it for your actual services.
Does a med-spa need different permits than a salon in DFW?
It can. A standard salon runs through the building permit, but a med-spa offering medical treatments may add health and accessibility requirements closer to a clinical space, depending on services and supervision. We confirm the review path before design to avoid an inspection surprise.
