- If any walls are going to be added or moved, now is the time to do that part of the project. If you are adding walls consider using steel studs. If you are installing a drop-in tub, the framing should be installed at this time.
- The next item to install is the bathroom ventilation. If there is forced air heating in the room, re-route ducts as required.
- Drain and vent piping is the next item which should be relocated, or installed as required for the installation of the bathroom fixtures.
- Hot and cold water lines should be installed as the next stage.
- Now install any electrical changes necessary for light fixtures, receptacles, whirlpool tubs, steam generators, ventilation and heating.
- Install any additional insulation and vapor barriers that may be required on the inside of outside walls.
- Install the (hang) drywall or other material on the ceiling.
- If you are installing a bathtub with a lip and/or a shower base and/or a shower or bathtub enclosure, they should be installed now. Make sure that you protect those items with drop cloths, cardboard or other material from the potential of items such as tile, falling and damaging the items. Install the drain lines to those bathtubs and/or shower bases.
- Shower and bathtub faucets and diverters they should be installed at this time.
- Now is the time to install the sub-floor material.
- Hang wall material and apply joint compounds (mudd) as required.
- Paint ceilings and walls. Do not forget to use proper primers and undercoats.
- Install your finished flooring material (I believe that the finished flooring material should go under the vanity, to maintain the proper height of the vanity as well as making an easier and neater flooring project. If you so desire you can install the vanity before installing the finished flooring material). If you are installing electric or hydronic radiant heating it should be installed with the finished flooring material. Once the finished floor is installed cover it with Melamine or plywood to protect it.
- If you are installing a drop-in bathtub, install the finished surface of the drop-in framing and then install the bathtub. Once the bathtub is installed use heavy drop clothes to protect it.
- If you are installing a vanity and countertop they should be installed now.Install the sink, and connect it to the drain and vent pipes.
- wall tiles and any in-wall towel bars and other accessories and grout. It is best to wait at least 24 hours from the time the tiles are installed to grouting. This gives the tile adhesive a chance to cure.
- If you have shower or bathtub doors, install them at this time.
- Baseboard, door trim and other moldings should be installed now.
- Install the toilet.
- Install switches and receptacles.
- Complete the installation of bathtub, shower and basin faucets. Install the showerhead.
- Install mirrors, medicine cabinets, light fixtures, electrical cover plates and grills over vent fans.
- If necessary, do paint touch-up work as appropriate.
- Apply caulking where appropriate.
- Using the correct anchors, install any wall mount towel bars and/or bathroom accessories.
