Master Bath Floor Plans

Small Bath Floor Plan

One of the most common bath layouts is a 9x5-foot space with a vanity, toilet, and tub-shower combo lined up next to one another. This narrow floor plan is an efficient option for a small space. It also helps reduce construction costs because all of the plumbing fixtures are contained within one wall.

To personalize your space, consider a furniture-style vanity or contemporary floating vanity instead of an off-the-shelf cabinet. Opt for a console-style sink with open floor space below to make the room feel bigger.

Another space-expanding tip is to replace the tub-shower combo with a large shower. Without a tub to stop your eye, the space feels larger. If you have a tub in another bathroom, gaining a plus-size shower in a master bath can increase the perceived value of a master bedroom suite.

Medium-size Bath Floor Plan

A second common floor plan places plumbing fixtures on two walls with the vanity and toilet on one side of the room and the tub or shower on the opposite wall.

This configuration typically offers more vanity size and style options. Including two sinks (or a double vanity) is a nice benefit for a shared master bath. Choosing a bigger vanity offers more countertop space and storage below. 

If you prefer to have a separate tub and shower, put them side by side to reduce running additional plumbing lines to each area. If you crave additional storage, opt for a large walk-in shower or a shower-tub combo and outfit the rest of the wall with a tall linen closet.

Large Bath Floor Plan

For a more luxurious bath experience, spread out your main bath fixtures in a 10x12-foot space (or larger). Place the bathtub under a window for a pretty focal point. Double vanities are a favorite feature in master bathrooms, allowing each person their own area.

Dedicate space on a third wall for a walk-in shower. A glass shower door will make the bathroom feel open. If you prefer more privacy, a frosted door in a tiled shower is cozy and stylish.

Closing off a small compartment for the toilet is a nice feature and provides extra privacy, while maintaining the decorative appeal of the space.

Dream Bath Floor Plan

For the ultimate bath, incorporate architectural elements, such as bay windows, to serve as a dramatic backdrop to a freestanding bathtub.

Place vanities on opposite walls to give everyone their own space without bumping elbows. If you have a long wall for a spacious vanity, consider lowering a 24-inch section of the countertop to create a dedicated makeup station. Leave space below the countertop open to store a stool or chair so you can sit while grooming.

A walk-in shower with a space for drying off keeps water contained in one area and reduces wet floors throughout the rest of the bath. A separate toilet area improves privacy and offers an out-of-the-way spot to store bathroom essentials.
