An alcove installation places a walk-in tub in the classic three-wall opening where a standard 60 inch bathtub used to sit. The tub is enclosed on the back and both ends, with only the front apron exposed. Every Ella tub fits an alcove, and most 52 and 55 inch models use an extension panel to fill the gap at one end so the finished installation looks built in.

How It Works

Most bathrooms were framed around a 60 inch tub, so that is the opening you are usually filling. Tubs that are 60 inches or longer fill the space on their own; a 60 inch tub such as the Ultimate is actually 59.5 inches, which is why it needs no extension panel. Most shorter tubs fill the remaining space with an Ella extension panel that mounts at the end of the tub frame. The walls above the deck are then finished with tile or a surround over an aftermarket tile flange so water runs back into the tub.

Ella tubs are not limited to alcoves. The same models can stand against one or two walls with an end panel closing the exposed side, which Planning the bathroom layout explains.

Which Ella Models Have It

Every Ella model fits a three-wall alcove. Which ones ship with or offer an extension panel, and the panel width for each, is listed in Extension panels and filler kits by model. A few models, such as the Front Entry and Mobile, have no extension panel, so the installer frames and finishes any remaining space instead. Always plan around the actual size on the spec sheet rather than the nominal name, and read Will it fit my alcove? before framing.

What to Know as an Owner

Alcove placement limits service access, because the plumbing end of the tub is against a wall. Ask your installer to add a wall access panel behind the plumbing end so pumps and drain connections can be reached without disturbing tile. Planning service access covers what to leave reachable and why the space around the tub must never be packed with insulation.

A few accessory details change in an alcove. A shower column installed on a tub with an extension panel uses the long 4 to 5 inch pipe connector to reach the wall. The 4-fold glass screen converts to a 3-fold screen by removing one section, which is how it fits a 52 inch tub in a 60 inch alcove with an extension panel. Mention the alcove and the panel when you ask the team about either accessory.

If you open a ticket about fit, have the width of the opening measured wall to wall at the back and at the front, the model name, and the actual size from the spec sheet. That lets the team confirm the extension panel and screen configuration for your order.
