AI picks by need

The established name for whirlpool and air-jet drop-in tubs.

What the AI looks for in Drop-In Bathtubs
- Deck construction
- The deck must support the rim along its full length, with access left for drain and pump service. An unsupported rim cracks, and a jetted tub needs a service panel.
- Bottom support
- Set acrylic tubs in a mortar or foam bed unless the maker specifies leveling feet only. Prevents flex, creaking and cracking.
- Rough-in dimensions
- Cut the deck opening from the maker's template, not from the tub's outer size. The rim overhang varies between tubs.
- Jet electrical
- Jetted and heated tubs need a GFCI-protected dedicated circuit. This is required by electrical code and the maker's instructions.
Brands that matter
- Kohler: Wide range of drop-in soakers and cast-iron drop-ins.
- American Standard: Acrylic drop-ins, with or without jets.
- Jacuzzi: Whirlpool specialist.
What to avoid
- Jetted tubs with no access panel to the pump.
- Setting an acrylic tub on bare subfloor.
