Choosing from the many types of bathtubs available means matching your bathroom layout, plumbing configuration, budget, and bathing preferences. An alcove tub that fits a 5-foot opening costs $200-$600. A freestanding soaking tub that anchors a master bathroom design costs $500-$3,000+. Each type serves a different purpose, fits a different space, and creates a different visual impact. Here is every common bathtub type, what it costs, and where it works best.

Alcove Bathtubs
The most common residential bathtub — installed between three walls with the front side exposed. Standard sizes are 60×30 inches or 60×32 inches, designed to fit standard bathroom alcoves. The tub doubles as a shower with a curtain or glass door. Alcove tubs cost $200-$600 for the tub alone and are the default choice in guest bathrooms, kids’ bathrooms, and standard hall baths.
Materials range from basic fiberglass ($150-$300, lightweight, budget-friendly, 10-15 year lifespan) to acrylic ($200-$500, warmer to the touch, better heat retention, 15-20 year lifespan) to enameled steel ($150-$400, extremely durable but heavy and cold to the touch) to cast iron ($400-$2,000, the heaviest and most durable option at 300-400 pounds that lasts 50+ years).
Freestanding Bathtubs
Freestanding tubs sit independently on the floor, exposed on all sides. They are the statement piece of master bathroom design — dramatic, sculptural, and the first thing guests notice. Shapes include classic clawfoot, modern slipper (raised at one end), pedestal, and flat-bottom designs. Sizes range from compact 55-inch models to luxurious 72-inch soakers.
Freestanding tubs cost $500-$3,000+ for acrylic and composite materials. Cast iron clawfoot tubs with restored enamel run $1,500-$3,500 from restoration companies or new from manufacturers like Kohler and American Standard. Installation requires floor-mounted plumbing (drain and faucet supply) rather than wall-mounted — plan plumbing rough-in during the design phase if converting from an alcove tub. A freestanding filler faucet ($300-$800) completes the installation as a visible design element rather than hidden behind a wall.
Drop-In Bathtubs
Drop-in tubs are rimmed tubs that sit inside a built surround or deck. The tub drops into a framed platform with a finished surface (tile, stone, or solid surface) on the deck and front panel. The finished surround hides the tub body and creates an integrated, custom look. Drop-in tubs range from $200-$1,500 for the tub, plus $500-$2,000 for the deck/surround construction and finish.
This type offers the most design flexibility — the surrounding deck can be tiled in any material, shaped to any dimension, and include features like wide ledges for candles and bath products, corner seating, or built-in grab bars. The trade-off is cost and space — the surrounding deck adds 6-12 inches to each dimension, making drop-in installations impractical in bathrooms under 60 square feet.
Undermount Bathtubs
Similar to drop-in but mounted from below the deck rather than resting on the rim. The tub edge sits flush with or slightly below the deck surface, creating a seamless, modern aesthetic. Undermount installation requires a reinforced deck structure because the tub’s weight hangs from the rim rather than resting on a support frame. This type is most common in luxury custom bathrooms where a clean, uninterrupted counter-to-tub transition is the design priority.
Corner Bathtubs
Corner tubs fit into the intersection of two walls, maximizing use of corner floor space while providing a larger bathing area than standard alcove tubs. Triangle-shaped and curved-front models range from 48×48 inches (compact) to 60×60 inches (generous). Corner tubs cost $400-$2,000 and work particularly well in master bathrooms where a separate shower handles daily bathing and the tub is reserved for soaking.
Many corner tubs include built-in whirlpool jets ($200-$800 additional) since the wider tub body accommodates jetted systems better than narrow alcove tubs. Consider noise levels and maintenance when opting for jets — whirlpool pumps produce 60-70 dB of noise and the jet lines require monthly cleaning with a system flush to prevent mold and bacteria growth in the plumbing.
Soaking Tubs
Soaking tubs are deeper than standard tubs (20-24 inches versus 14-16 inches for a standard alcove tub), allowing full-body immersion. Japanese-style soaking tubs (ofuro) are the deepest at 22-27 inches, designed for sitting upright rather than reclining. Soaking tubs come in freestanding, drop-in, and alcove configurations. The key specification is water depth — look for tubs with an overflow drain positioned high enough to allow deep filling.
A standard 60-inch alcove tub holds 30-40 gallons of water. A deep soaking tub holds 60-80 gallons. This means your water heater must deliver 60-80 gallons of hot water for a full bath — a 40 or 50-gallon tank-style heater cannot fill a large soaking tub without running cold partway through. A tankless water heater or a larger tank (65-80 gallons) may be necessary when upgrading to a soaking tub.
Choosing the Right Type
- Standard family bathroom: Alcove tub/shower combo. Practical, affordable, space-efficient. The right choice for most secondary bathrooms
- Master bathroom redesign: Freestanding tub as a design focal point, paired with a separate walk-in shower. The dominant trend in master bathroom renovation
- Luxury bathroom: Drop-in or undermount tub in a custom-tiled surround. Maximum design customization and a built-in, architectural feel
- Small bathroom: Alcove or compact freestanding (55 inches). Every inch matters — measure the bathroom footprint carefully before selecting a tub size
- Relaxation-focused: Deep soaking tub or Japanese ofuro. Prioritize water depth and body immersion over length and reclining room
