You’ve got the chairs picked, the mirrors ordered, and the color bar laid out. Then someone asks the question nobody prepares you for: how many hair salon sinks are we installing? If your answer is “however many fit,” this guide is for you. The wash area is the most expensive part of a salon to change later — moving one sink means drywall, a plumber, and lost bookings. Getting the count and the plumbing right the first time saves you real money.
How Many Hair Salon Sinks Does Your Salon Actually Need?
There’s no code for this, but there’s a rule of thumb that works: one sink for every two to three stylists who wash hair. If every chair in the shop does shampoos and blowouts, budget one sink per two chairs. A four-chair salon runs fine with two sinks; an eight-chair shop usually needs three or four, depending on how many clients each stylist washes per day.
Here’s why that math works: a wash and wrap takes fifteen to twenty minutes per client. Two stylists sharing one sink means a wait every time they’re both on a shampoo — and waiting clients notice. If you run color services, add one dedicated sink near the color area for toners and gloss rinses. You don’t want a toner client walking across the whole salon in foils.
Where the Sinks Go: Layout Mistakes to Skip
Put sinks on a shared plumbing wall if you can. Back-to-back or side-by-side sinks on one wall cut installation cost dramatically — one water line and one drain run serves the whole row. Space them 30–36 inches apart so stylists aren’t bumping elbows.
Ergonomics matter more than looks. The bowl rim should sit around 32–34 inches off the floor — high enough that a stylist isn’t hunched, low enough that the client’s neck isn’t cranked. That’s why the sink and chair have to be bought as a matched pair, not separately. If you’re unsure about sizing, our shampoo bowl and chair combination guide walks through the dimensions that actually line up.
Two concrete layouts worth copying: a four-chair salon usually puts two sinks side by side on the back wall, with the shampoo chairs angled slightly toward them; an eight-chair shop often runs a row of four sinks with chairs alternating. If space is tight, a corner arrangement with two sinks at 90 degrees works — just keep the 30–36 inch spacing, not the 20 inches some installers try to squeeze in.

The Plumbing Reality Nobody Mentions
Before you order anything, check your hot water. A 50-gallon tank handles roughly four to six back-to-back washes before it runs lukewarm; busier salons should look at tankless. Water pressure of 40–60 psi is the sweet spot for a sprayer that actually rinses.
Drain slope is another thing nobody sees until it’s wrong — you need about 1/4 inch of fall per foot of drain line, and every line should have a hair trap. A good bowl is also at least 8–9 inches deep at the back, so the client’s head rests in water instead of on a puddle. Wall-mounted sinks need a stud to bite into; floor-mount pedestals need clearance in front for the chair. Here’s the honest comparison:
| Setup | Best for | Installation | Typical 2026 cost |
|---|---|---|---|
| Wall-mounted sink | Small spaces, easy floor cleaning | Wall bracket + plumbing; needs a stud | $200–$500 per sink |
| Floor-mount pedestal | Heavy daily use, bigger wash areas | Bolt to floor + plumbing | $250–$550 per sink |
| Portable tank station | Booth renters, pop-ups, no plumbing | None — water tank + drain bucket | $300–$700 per unit |
Add $200–$600 per station for a plumber if you’re not doing the work yourself. All in, a permanent wash station lands around $500–$1,200 by the time the sink, faucet, and labor are done.
What to Look for in the Sink Itself
Deep bowl so water doesn’t splash, an integrated neck rest, a lever or spring-controlled faucet you can operate with a wrist, and a sprayer on a hose long enough to reach the back of the head. Order the sink and faucet together, and don’t let the plumber leave without testing the sprayer reach — a hose that’s 12 inches too short is a daily annoyance you’ll curse for years. Ceramic looks great and cleans up beautifully; acrylic is lighter and quieter. Skip anything with glued-on trim — it’s the first thing to fail.
If you’re outfitting from scratch, this is where buying factory-direct pays off. Nova builds wash stations and shampoo beds to order: MOQ is just 1, so sample orders are welcome, production takes 10–15 days, and DDP door-to-door shipping gets your order to a US address in about 4–6 weeks by sea — with a one-year warranty on top.

FAQ
Can I install a hair salon sink without a plumber?
If you’re handy, a wall-mount sink with an existing supply and drain nearby is a weekend job. If it means opening walls or running new lines, pay the plumber — leak damage costs way more than the call-out.
Wall-mount or floor-mount for a small salon?
Wall-mount. It frees floor space for the chair and makes cleaning under the sink trivial.
How long does shipping take if I order from Nova?
About 4–6 weeks DDP door-to-door by sea, with production taking 10–15 days before that. Sample orders (MOQ 1) ship the same way.
