The wall behind the toilet can be almost any height. For a standard toilet height of 15 in., make the wall a minimum height of 43 in. If you’d like a higher toilet, make the wall that much higher. Or, make the wall go all the way to the ceiling. We built a short wall to conserve space and to create a shelf and a mirror alcove. The wall at the opposite end of the shower can be any height as well. We made it the same height as the toilet/sink wall so we could line up the accent tile and make a convenient shower shelf.
Time to jump into your DIY pants. I am going to start off with the easiest and most prevalent DIY project around the house. Believe it or not, new paint can transform your bathroom from 1980s drab to 2010s fab. Whether you go bold with dark blue or casual with stripes, new paint will not only give new life to an outdated bathroom, but make it feel larger as well.
For your remodeled bathroom to operate well, it’s critical to install vent and drain lines of the proper size and slope. Use a 2-in. line to drain the shower and 1-1/2-in. line to drain the sink. The vents for the sink and shower can be 1-1/2-in. pipes, but a toilet should be vented with at least 2-in. material. Make sure that the drain lines drop 1/4 in. for every foot of travel toward the main stack.
Proper ventilation will prevent moisture from getting trapped in the bathroom, which can lead to mold and mildew growth. Extract moisture by installing a ducted exhaust fan on a timer. Most timers allow you to set the fan for 15 to 60 minutes to remove heat, steam and condensation. Choose a fan according to the cubic feet per minute of air it moves.

Flank the mirror with fixtures placed at eye level (around 66 inches), ideally spaced 36 to 40 inches apart. Try to see fixtures in action before you buy to make sure the amount and quality of light is sufficient. If there's no room for side sconces, install a long fixture on the wall above the mirror. Don't rely on a recessed ceiling fixture (think Dracula face).

A DIY bathroom remodel is a big project. If you can only work weekends, your bathroom will be out of commission for two months or more. You’ll need all your expertise as an experienced do-it-yourselfer because you’ll have to tackle electrical, plumbing, tiling, drywalling, taping and even exterior siding. In this DIY shower remodel article, we’ll deal mostly with the nuts and bolts of ripping out existing plumbing and replacing it correctly with new, easily installed PVC piping.
