The special-order fixtures, fittings, shower pan, tile and glass block panel can take weeks to get in hand, so do the necessary legwork and ordering well in advance. Before gutting the bathroom, check to make sure that there are shutoffs for all the fixtures or a master shutoff for the entire bathroom. If not, buy ball valve shutoffs sized to fit your pipes. Then turn off the main water supply line where it comes into the house from outside, cut the pipes feeding the bathroom and install the new shutoffs right away (see Photo 7).
Turn off the main water supply to the house, and in a convenient location, cut the hot and cold water supply pipes for the bathroom. Also cut out and remove all the existing water lines and fittings in the bathroom. Finally, cut out and remove the vent section leading to the sink and the main stack 5 in. below the vent tee. Stuff rags into open drain lines to keep sewer gas out of the house.

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.

Follow Fig. B, for the new drain/vent plan. The new shower drain is vented separately into the main stack (Photos 10, 12 and 13). Most bathrooms have the main stack positioned directly behind the toilet. The wall-mounted toilet shown here cannot be positioned directly behind the stack because there’s not room for the necessary elbows. If your stack is more than 12 in. to the side of the existing toilet, you can keep the same location for the wall-hung toilet. But if it’s directly behind it, you’ll need to swap the sink and toilet locations like we did.
