Here’s a word of warning, though. It’s going to take more time than you think. Why? Your bathroom may be the smallest room in the house, but you’re going to have to paint slowly and gently around the window, the tub or shower, the sink, the mirror, the toilet, the switchplates, the wall corners, and the floor. This takes time and patience (and a good supply of painter’s tape), so make sure you keep this in mind when planning your renovation.
Low-flow toilets, which use 1.6 gallons of water per flush, are required by law in all new and remodeled baths. Pressure-assisted toilets effectively clear the bowl with one flush, but make considerable noise in the process. Gravity models sometimes require two flushes to clean the bowl properly. For maximum efficiency, choose a bowl with a large water surface. Make sure there's sufficient space around the toilet for comfortable access—ideally, at least 16 inches from the centerline of the toilet and walls or fixtures on either side. Also allow at least 30 inches from the front of the toilet to the nearest object.
A full bath requires a minimum of 36 to 40 sq. ft. The finished room must measure at least 5 ft. in one direction to accommodate a tub. Building codes typically require 32x32 in. (finished dimensions) for a shower; if you have the space, larger is better. Just make sure the shower is large enough so you can comfortably raise your arms and bend over in the space.
Your creativity will show with adding or replacing floor tile and wall tile with a bathroom remodel. The choices of polished or textured, subtle or bold, patterned or solid and single- or multi-colored are just the beginning of your options. Modify the traditional brick pattern to install subway tile vertically, or consider a herringbone layout to add visual interest to simple tile designs.
