How do I Rebuild the Bathroom in a Travel Trailer?
Repairs, leaks and old, worn paneling can age your RV bathroom. Using a few simple tools and restorative processes, you can rebuild your RV bathroom in less than 24 hours. For a two-pronged attack, it is best to repair the interior paneling as well as add new furnishings and facilities to improve overall appearance and utility.


Difficulty: Moderately Challenging

Things You’ll Need:
  • Sealing
  • Caulk
  • Silicone
  • Woodwork
  • Wall paneling
  • Filler
  • Baton strip
  • Nails
  • Drill
  • Saw
  • Fiberglass insulation
  • ¾-inch plywood
  • Screws
  • Toilet bowl seal
  • Sewer vent
Step 1
Repair damage from a leaky bathroom. Remove trim, paneling and insulation from the walls. Replace damaged studs. Chip away or pull off dried sealing. Apply a new layer of sealing with new caulk and silicone. Do not reinstall the old paneling. Proceed to step 2.
Step 2
Install new woodwork and wall paneling. Use filler to fill holes, scratches and other surface damage. Apply matching baton strip in the same material finish. Work around the venting pipe, installing each piece of wood paneling with two nails. Because the amount of space you have is limited, pre-drill holes outside of the RV and then nail them into place once inside.
Step 3
Pull up or cut out old flooring. Be careful not to cut through the steel cross beams along the length of the floor or the outer sheet metal of the RV. Add a layer of fiberglass insulation to the floor. Install ¾-inch plywood to the insulated floor with coated deck screws. Countersink the screws for an all-around smooth surface.
Step 4
Replace toilet bowl seals, which can thin over time. Lift the toilet from the floor. You will immediately see the toilet bowl seal between the mounting flange and the toilet. Peel away the seal and wipe away any muck from the flange and toilet base. Attach a new seal over the flange and affix it with plumber's sealant. Fix the toilet over the bolts and lower it into place. Bolt the toilet down.
Step 5
Add a new sewer vent. Unscrew the cap to the gray water tank vent from atop the RV roof. Add a silicone sealant to the groove around the vent opening. Fix the T vent, which is shaped like the letter T, securely over the gray water tank vent. Cut a small piece of screening and fasten it over the openings using wire ties.
