Two weeks before opening, the shampoo bed is still in its crate and the plumber keeps asking whether you want a floor drain or a wall drain. Shampoo bed installation is the one job in a salon build where guessing costs real money — tearing up a finished floor to move a drain runs $800 to $2,500. Here is how to plan it once and get it right.
First decision: plumbed or no-plumbing
Plumbed stations look and feel like a traditional backwash: permanent water supply, permanent drain, nothing to empty. No-plumbing set-ups use a tank you fill and empty, and they let you open in a rented space without touching the plumbing at all.
| Set-up | Plumbing needed | Typical install cost | Best for |
|---|---|---|---|
| No-plumbing / portable shampoo station | None | $0–$150 | Rentals, mobile stylists, pop-ups |
| Freestanding bed, flexible hose to existing drain | Drain + supply nearby | $150–$450 | Adding one station to an existing room |
| New plumbed bed with new floor drain | Full plumbing + concrete or floor work | $800–$2,500 | Purpose-built wet room, busy salons |
| Head spa bed with tank and pump | Minimal — power only | $50–$200 | Small studios growing into head spa services |
Space and clearance before anything else
Measure the footprint, then add the human space around it: 24–30 inches of working room on the service side, and enough reclined length behind the bowl for the client’s legs. A shampoo bed typically runs 70–78 inches long, with the bowl 10–14 inches deep — check the exact numbers against your room in our shampoo bed dimensions guide before you commit, because a bed that fits the wall but not the doorway is a very expensive mistake.
Drain and water supply
- Drain height. Keep the trap below the bowl outlet. A drain that sits higher than the outlet will pool dirty water, and you will smell it by week three.
- Slope. Waste pipes want a fall of about 1/4 inch per foot. Flat runs are the most common cause of slow backwash drains.
- Access. Leave a removable panel or a service gap. You will need to clean a hair trap eventually — see shampoo sink care and hair traps.
- Water temperature. Standard faucets need both hot and cold lines. If your water heater is far away, a thermostatic or inline heater keeps the first rinse from running cold.
- Hose routing. Use a flexible braided hose and a shut-off valve at each bed so one repair does not close the whole wet room.
Electrical needs for electric shampoo beds
If you choose an electric-lift bed, plan the outlet before the bed arrives. Nova’s electric beds run on 110V-240V dual voltage with CE certified components, so they work in US salons and in overseas locations without a transformer. Put the outlet on a GFCI circuit, keep the cord out of the splash zone, and leave 12–18 inches of slack so the bed can be pulled out for cleaning. A dedicated circuit is worth the extra $150 if the room also runs dryers or steamers.
Installation sequence
- Set the bed in its final position before connecting anything. Mark the footprint on the floor with tape and walk the route clients will take.
- Level the frame. An unlevel bed drains poorly and the lift motor strains on one side.
- Confirm the drain fall and trap height, then connect the waste.
- Connect water supply and fit the faucet, with shut-off valves accessible.
- Seal the bowl-to-cabinet joint and the wall gap. Silicone, not grout — grout cracks the moment the bed flexes.
- Run a full test cycle. Fill, run the sprayer, check for weeping under the bowl, then run the lift through its full range twice.
- Check the weight rating. Nova beds and chairs are built for a 300kg weight capacity, so a heavy client plus water load is not a concern when the bed is installed on a level floor.
What it costs in 2026
A no-plumbing or portable shampoo station starts around $300–$900. A freestanding plumbed shampoo bed runs $700–$1,800 factory direct, and a full head spa bed with tank and pump $1,500–$3,500. Add $150–$600 for a plumber on a straightforward connection, and more if a new drain has to be cut into the floor.

Buying without the middleman
Nova supplies shampoo beds factory direct with MOQ 1 and sample orders available, so a single-salon owner can test one bed before outfitting three rooms. Production time is 10–15 days and shipping is DDP door-to-door to the USA, typically 4–6 weeks by sea, with a one-year warranty on every bed. That combination matters more than it sounds: on a build schedule, knowing the exact arrival week lets you book your plumber with confidence instead of paying for a standby visit.

FAQ
Can a shampoo bed be installed without a floor drain?
Yes. You can tie into an existing wall drain, or use a no-plumbing station with a tank and pump. A floor drain is the most forgiving option, but it is not mandatory for a single station.
How much space does installation really need?
Plan on the bed footprint plus 30 inches of working room, plus clearance for the reclined client. Roughly 8 ft by 5 ft is a comfortable single-station envelope.
Do I need an electrician?
Only if you add an outlet or a dedicated circuit. Nova’s electric shampoo beds run on 110V-240V dual voltage with CE certified components, so if a suitable GFCI outlet already exists, installation is plug-in.
