Bathroom Remodeling | Planning the Perfect Half-Bath

Adding a Half Bath

Bathroom Remodeling | Adding a half bath to a home is one of the most common bathroom remodeling requests I get. People want to increase the value of their houses, of course, but what most of my clients really want is a bathroom that’s convenient for their guests to use but doesn’t compromise anyone’s privacy. (Who wants their friends to see dirty laundry and prescription bottles, anyway?) Depending on your house’s layout, there are several ways to add a half bath by carving out space from your existing floor plan. What I’ve presented here are three options that have worked for my clients: a bathroom tucked underneath a stairway, one carved from a garage, and another nestled inside a gabled attic dormer. Other solutions I’ve used include fitting a half bath into an oversize storage closet and splitting a large full bathroom remodeling project into a half bath and smaller full bath.No matter where you decide to put it, there are a few key factors you should keep in mind as you’re planning this common bathroom remodeling project.

Bathroom Remodeling: Dimensions

A half bath needn’t be large. You will have enough space if you can find a spot in your house that’s about 3 to 4 feet wide and 6 to 8 feet long. If it’s any smaller, it will be uncomfortable for people to access. A larger half bath is unnecessary, and it’s not likely that you’d find that much “extra” unused space in your house.

Bathroom Remodeling: Functional Elements

A half bath needs to contain, at a minimum, a toilet, a sink, and a mirror. Having an under-sink cabinet or another storage area for extra tissue paper, hand towels, and soap is nice, but if space is tight, these items can be stashed elsewhere.

Bathroom Remodeling: Plumbing

Obviously, a half bath needs running water as well as drainage and ventilation. For budget reasons, try to locate your new half bath as close to existing water and sewer connections as possible. One of the cheapest options is to place it where it can share a wall with an existing bathroom. For older houses built on piers or over basements, new plumbing lines can be placed below the main floor fairly easily. Houses built on slab foundations, though, will require some jackhammering and patching of the slab to connect existing plumbing lines to the new space, which adds to the project’s cost.

Ventilation and Electrical Requirements

Current codes require either an operable window or an exhaust vent in every bathroom remodeling project to properly ventilate the space. Also, electrical outlets will need to be installed on a GFI circuit, which provides extra protection against shock in wet areas of the home. These requirements are a consideration for older homes that may not have up-to-code electrical or ventilation systems.

Adequate sound insulation is a key concern for any bathroom, but it’s especially important for half baths near living or dining areas where you may be entertaining guests. This can be accomplished inexpensively by adding sound insulation in a shared wall or by wrapping water pipes, vents, and drains with a sound—absorptive material before closing up the walls.

Visual privacy

Many people prefer to enter and exit the bathroom with some degree of privacy. If possible, locate the half bath’s entry so it’s not directly in sight of adjacent living spaces, or shield it from view so that guests can come and go discreetly. You may be able to solve this problem simply with a strategically placed screen or room divider or by rearranging furniture in the nearby room so that seating faces away from the door.

bathroom remodelingUse Corners to Gain Space

Outfitting a small bath with storage and lighting and giving it a little style can be a real challenge. This sleek version of the traditional medicine cabinet fits snugly in any 90-degree corner to save space; a pair can be used on both ends of a vanity wall. The unit comes with a full mirror, adjustable glass shelves and incandescent or halogen lighting. With sizes up to 40 in. tall and 20 in. wide, the all-aluminum cabinet works as well in a master bathroom as it does in a powder room.

Tucked Under a Stairway

For privacy’s sake, it works best in homes with an enclosed foyer that opens into adjacent entertaining spaces. The two biggest obstacles are providing ample headroom (I recommend a minimum height of 5 feet above the toilet; check your local codes for height requirements) and ventilation (an exhaust vent will need to be run to the exterior). Place the sink or vanity on the tallest wall so hand washers won’t bump their heads.

Carved Out of a Garage

We were able to slice out a portion of the tool room in a client’s garage to create a half bath that serves the adjacent kitchen as well as the garage and outdoor areas of the home. Because of the number of doors in the home’s rear entry, access to the half bath is via a sliding pocket door, which solves the problem of doors banging into one another or unintended “door traps” that result when doors are left open.

bathroom remodelingFitted Within a Dormer

This is a good option for houses that have a decorative gabled dormer on the attic level. If the ceiling heights within the dormer are at least 7 feet at the interior ridge, and if there’s at least 5 or 6 feet of width between walls at least 5 feet tall, you’ll have room for a half bath. If the dormer is at least 5 feet long you can even add a bathtub; in this example I put in a tub and added a shed dormer above to bring in natural light. – This Old House
