Whirlpool AST108-WH-UM Undermount Air Bath 72x48.25 White

Product Description

The WHIRLPOOL AST108-WH-UM is an acrylic undermount air bath tub finished in white and sized at 72 x 48.25 inches. Air bath units use pressurized air jets to deliver a full-body hydrotherapy experience distinct from traditional whirlpool circulation. This model is designed for undermount installation, meaning the deck or surround is built over the tub rim for a clean, finished appearance. Plumbers and finish carpenters typically collaborate on the rough-in, framing, and final trim work required for this installation type.

This tub is suited for residential master bathroom applications where a large-format soaking and air therapy fixture is specified. The 72 x 48.25 inch footprint accommodates two occupants and fits standard alcove or open-floor plan configurations that have been framed to the appropriate rough opening. The white acrylic finish is a standard color selection compatible with common fixture and tile palettes in residential builds and remodels.

Key Features

• Undermount installation style for a flush, deck-integrated appearance
• Air bath hydrotherapy system with pressurized air jet delivery
• White acrylic construction for durability and surface consistency
• Large 72 x 48.25 inch footprint designed for two-person use

Compatibility

Designed as an OEM-style undermount air bath fixture for residential bathroom installations requiring a 72 x 48.25 inch rough opening.

Installation Notes

Undermount tub installation requires a structurally sound support frame built to the manufacturer rough-in dimensions prior to setting the unit. A licensed plumber should handle all drain, overflow, and supply connections in compliance with the applicable IPC or local plumbing code. Disconnect all electrical circuits serving the air bath system before performing any service or inspection of the blower or jet components. Do not overtighten drain and overflow fittings against the acrylic shell, as acrylic is susceptible to stress cracking.
