Bathtub Buying Guide: Alcove, Freestanding, Drop-In & Soaking Tubs
The bathtub is often the centerpiece of a bathroom design. Whether you're replacing an existing tub or planning a new installation, the type, material, and size you choose affects everything from daily comfort to long-term value. Here's what you need to know.
Bathtub Types
Alcove
Fitted between three walls. The most common type in American homes. Typically 60" x 30-32". Includes an integral flange for tiling. Can double as a shower (shower/tub combo). Most affordable installation since it fits standard bathroom layouts.
Freestanding
Stands on its own, away from walls. The luxury statement piece — available in slipper, pedestal, and modern flat-bottom styles. Requires floor drain access and a freestanding or wall-mount tub filler. More expensive to install but delivers dramatic visual impact. KOHLER's Underscore and Memoirs freestanding tubs are top sellers.
Drop-In
Drops into a built platform or surround. The rim sits on the deck. Offers flexibility in size and shape since the platform is custom-built. Popular for large master bathrooms with a tub deck or surround.
Undermount
Mounted below a deck with the rim hidden. Creates a seamless, clean look. Similar to drop-in but with the rim concealed. Premium aesthetic.
Corner
Designed to fit into a corner, saving floor space while offering a generous bathing area. Good for mid-size bathrooms where a freestanding tub won't fit but you want more than an alcove.
Materials
| Material | Pros | Cons | Price Range |
|---|---|---|---|
| Acrylic | Lightweight, warm to touch, wide color/shape options | Can scratch, yellows over decades | $300-$2,000 |
| Cast Iron (enameled) | Extremely durable, retains heat, classic feel | Very heavy (300-500 lbs), limited shapes | $800-$3,000+ |
| Fiberglass | Most affordable, lightweight | Less durable, flexes, shorter lifespan | $150-$500 |
| Engineered Stone / Composite | Luxurious feel, excellent heat retention | Extremely heavy, expensive | $3,000-$10,000+ |
Sizing Guide
- Standard alcove: 60" L x 30-32" W x 14-16" soaking depth. Fits most existing bathroom layouts.
- Deep soaking: 14-20"+ soaking depth. Look for tubs with a deeper basin if soaking comfort is the priority.
- Freestanding: 55-72" L, 27-32" W. Measure your bathroom carefully — freestanding tubs need clearance on all sides and access for plumbing.
Whirlpool, Air & Soaking
- Soaking (no jets) — Simple, quiet, low maintenance. Just hot water and relaxation.
- Whirlpool (water jets) — Targeted water jets massage muscles. Require more maintenance (cleaning jets, pump).
- Air bath (air jets) — Gentle bubbles from hundreds of small air jets in the floor. Quieter than whirlpool, easier to clean.
- Combination — Both whirlpool water jets and air jets. Maximum hydrotherapy.
Our Recommendation
For a standard bathroom, a 60" acrylic alcove tub is the practical, affordable choice. For a master bathroom centerpiece, a freestanding acrylic or cast iron tub makes a stunning statement. If soaking is your priority, focus on soaking depth (14"+) over overall tub length. We carry KOHLER, Delta, and other premium tub brands.
