How to Choose a Freestanding Tub
Part of our Bathtubs guides.
Freestanding tubs look effortless in photos, but they are one of the few bathroom purchases where a wrong measurement turns into a real problem: they are heavy, bulky and expensive to ship back. Work through these six questions before you order.
1. How much floor space do you actually have?
Measure the area where the tub will sit, then subtract clearance. Leave at least 6 inches between the tub and any wall so you can clean behind it, and ideally 8-12 inches so the tub reads as freestanding instead of crammed in. Also check the walkway: you want roughly 30 inches of clear floor in front of the tub to step in and out safely.
2. What length is comfortable?
| Tub length | Best for |
|---|---|
| 47-55 in | Small baths, seated soaking, kids |
| 59-60 in | Most adults, compact master baths |
| 66-67 in | Tall adults, full recline, shoulders under water |
| 70 in + | Large bathrooms, two-person soaking |
If you are tall, the 67-inch class (like VEVOR's two acrylic soakers) is where full-recline comfort starts.
3. Can your water heater fill it?
Tub capacity is listed in gallons to the overflow. You will not fill it all with hot water, because you mix in cold, but a 60+ gallon tub still needs a lot. A standard 40-50 gallon tank heater can run short on a big tub, especially if someone showered earlier. Tankless heaters fill slowly but never run out. Check your heater before buying the biggest tub.
4. Can your floor hold it?
Water weighs about 8.3 lb per gallon. A 60-gallon fill is roughly 500 lb of water, plus the tub and the bather. On slab or ground floors this is rarely a concern. On upper floors of older homes, ask a contractor to check the joists, especially for stone-resin or cast-iron tubs, which are far heavier than acrylic.
5. Where will the drain go?
Freestanding tubs drain straight down through the floor. The drain hole must land between joists and connect to your drain line. Moving it can be cheap on a crawlspace and costly on a slab. Ask your plumber before you choose a tub with a center vs end drain.
6. Which tub filler?
A freestanding tub has no deck for a faucet. Your options are a floor-mount filler (most common, needs supply lines through the floor), a wall-mount spout (only if the tub sits near a wall) or a deck-mount on tubs with a faucet ledge. Budget $100-$300 for the filler and plumbing labor on top of the tub.
Acrylic vs other materials
Acrylic (fiberglass-reinforced) tubs are lightweight, warm to the touch and repairable, which is why most budget and mid-range freestanding tubs, including VEVOR's, use it. Stone resin and cast iron hold heat longer but cost and weigh much more.
Shapes and styles
- Oval: the most common, comfortable at both ends, suits modern and transitional rooms.
- Slipper: one raised end for reclining.
- Clawfoot: vintage look, raised on feet; easier to clean under.
- Rectangular: crisp modern lines, more interior space.
Interior dimensions matter
Exterior length doesn't tell you the bathing length. Sloped backs and thick walls reduce interior space. Check the listing's interior length and depth to overflow; a deeper overflow means a deeper soak.
Frequently asked questions
How much space do you need around a freestanding tub?
At least 6 inches from walls for cleaning, and about 30 inches of clear floor in front for safe entry.
Is a 60 or 67 inch tub better?
60 inches suits most adults and smaller rooms; 67 inches gives tall people room to fully recline.
