Toilet Upgrade on Laminated Floor

The porcelain toilets weigh 30-40lbs more than the plastic which weighs about 3-5lbs. The added weight of the toilet will be on top of the user's weight. I do not know what the floor is designed for other than it is not designed for much.

I would appreciate insight from those who have actually made this mod to a foam laminate floor. I do not value conjecture as experience has taught me to proceed cautiously with matters that involve the integral elements of a coach, like a floor (especially a floor that is prone to weight-related failures).

JMO but you're imagining an issue that isn't as the toilet is actually supported by the flange, not the floor itself. As mentioned by another poster just sitting on the toilet obviously increases the downward force far more than would the difference between an all plastic vs plastic / ceramic toilet.

RV toilets are available in all plastic or plastic with a ceramic bowl and are universally interchangeable. If you'd prefer the latter a model like the Dometic 310 would easily replace an all plastic model like the Thetford AquaMagic V and the kit includes a rubber seal that would allow for any differences in how the toilet sits atop the flange.

Thank you, I am aware of this. My question is about the integrity of the laminated floor which is substantially less capable of weight bearing versus a 5/8 plywood floor. I want to know if anyone has experience with adding the weight of a porcelain toilet to a laminated foam floor. Will a foam floor handle the added weight? The porcelain toilets weigh a lot more. I am concerned about how easily these floors bow, divot, and flex. The laminated floor is not a substantial design for weight bearing.

Like countless others, we have already had to take measures to mitigate the floor's deterioration caused by normal use. Actually, we baby our TT, and the floor still presents all of the tell-tale deficiencies common to laminate floors.

Unless your floor is in bad shape, it shouldn’t be a problem. I wouldn’t have any qualms about doing that in our camper.
