Repair wet bathroom flooring

Hi all, we recently acquired a 71 caveman camper with a shower/toilet combo (wet bath?) and the PO never used the shower, so he cut part of the floor to fit it into his small midsize truck.

Question is, can I repair the floor pan with FRP or should I just yank it out to replace the whole pan?

  • With the large hole, the original owner didn't have ventilation issues when he was using the crapper.
  • At least being in 'the Land of Enchantment' you probably don't have a water intrusion / rot issue. Last time I hunted there I was always thirsty and drinking lots of bottled water....

    For 400 bucks, anything within reason goes. If it don't come out well, there is always the landfill.
  • Pretty much my current dilemma. FRP is cheap, a single sheet would let me fix the hole.

    The PO basically just cut off 1/4 of the pan, plus its almost perfectly square so I don't have a ton gaps to seal.

    I considered using a product like flexseal or some other spray/roll on rubber liner after the repair with frp.

    Paid ~400 for the whole camper
  • Additionally, of the suitcase toilet is self contained, upgrade to a Thetford Cassette toilet. I know my next unit will have one.
  • RV Parts Country has them in all different sizes, however they aren't cheap. I guess it would depend on how much the unit cost initially and how 'motivated' you are to replace it.
  • Where are you going to find a replacement shower pan for a 1971 camper, let alone a specific brand and model of 1971 camper?

    I couldn't find a simple square shower pan anywhere near the right size that didn't cost 25% of what I paid for the whole camper, and mine was only 10 years old at the time.

    A thetford will work in place of this one? The base of this one is the black tank for it. There's a valve at the bottom, that drains it down to the cleanout.
