Freestanding Bathtub Buying Guide: Sizes, Materials and Installation

A freestanding tub is the centerpiece purchase of a bathroom remodel, and the one buyers most often get wrong on the practical details: weight, drain position and actual soaking depth. This guide covers what matters before you fall in love with a shape.

Size: measure the room, then the doorways

Common freestanding tubs run 55 to 72 inches long. A 67 to 69 inch tub, like the popular Wyndham Collection Clara 69 inch soaking tub, fits most primary baths while leaving walking room. Leave at least 4 to 6 inches of clearance from walls for cleaning, more on the faucet side. Then check the path: stairwells, door frames and hallway turns have ended more tub deliveries than any other obstacle.

Soaking depth is the number that matters

Overall height tells you little. Look for the measurement to the overflow drain, which sets the real water depth. A proper soak wants 14 to 15 inches of water over the deepest point. Japanese style soaking tubs trade length for depth at 22 inches or more.

Materials compared

• Acrylic: light (60 to 100 lb), warm to the touch, repairable, and the best value. The majority of quality freestanding tubs sold today, including most Wyndham Collection and ANZZI models, are reinforced acrylic.
• Stone resin / solid surface: matte finish, excellent heat retention, 150 to 300 lb. The premium look of stone without the extreme weight.
• Cast iron: unmatched durability and heat retention, but 300 to 500 lb empty. Verify floor loading before ordering.
• Copper and specialty metals: statement pieces with artisan pricing.

Weight and your floor

Water weighs 8.3 lb per gallon. A tub holding 60 gallons adds roughly 500 lb of water to the tub weight, plus the bather. Standard modern framing handles most acrylic and resin tubs; for cast iron or stone on an upper floor or older joists, have a contractor confirm loading first.

Plumbing: budget for the faucet too

Freestanding tubs usually pair with a floor mounted filler, which requires supply lines routed under the floor: a real plumbing job, typically $500 to $1,500 in labor beyond the faucet itself. Wall mounted fillers can reduce cost if the tub sits near a wall. Confirm whether your tub includes a drain kit and whether the drain position matches your rough-in.

What should you spend?

Quality acrylic freestanding tubs run about $900 to $2,500. Stone resin runs $1,800 to $4,500. Our current range includes soaking tubs from roughly $999 to $2,400 from Wyndham Collection and ANZZI, with free shipping on all of them.

FAQ

Do freestanding tubs lose heat quickly?

Acrylic holds heat well; stone resin and cast iron hold it longer. Any tub loses most heat from the water surface, so a deeper, narrower shape stays warm longer than a wide shallow one.

Can I install one myself?

Setting the tub is a two person job. The floor mounted filler and drain hookup are licensed plumber territory in most jurisdictions.

Whirlpool jets or air jets in a freestanding tub?

Both exist but add cost, noise and maintenance. Most designers now specify a pure soaking tub for the primary bath.
