Thor Aria wet Basement floor replacement

Has anyone done the basement floor replacement themselves? Would like to hear your thoughts on the best way to do the work. What works and what doesn't. I would prefer to have the work done by someone but based upon the quality of the warranty work I had done, I should be able to do a much better job. thanks.

Hello! We had to replace the basement floor in our 2017 Venetian. Wasn't hard, but did take some time. I've attached some pics.
We replaced the wood with treated and completely sealed all the sections all the way around.

Thanks for your response. How did the plywood go to the white color? Is it paint or an overlay?

Its an overlay. You can get it at about any home improvement store. Its like a shower liner. Its usually by where they keep their paneling.
I used the adhesive thats made to glue that overlay material to wood. Worked very well!

Thor basement floor replacement

I replaced two full storage bays on mine with 3/4" solid PVC sheet, available from Home Depot or Lowes. It is like the Azek product, but a different brand that is available in the large sheets. I bought it in 4'x8' sheets and cut it to fit. It has a pebble grain finish on one side that matches the original finish. It is much stronger than the original plywood and can never rot.

The hardest part was the removal of the old plywood. I found that using an automotive floor jack worked easily from underneath to push it up and break it free. Then I removed the fasteners with vice grips. If they break off, just unscrew from the bottom by gripping the threads.

I cleaned the metal of old caulking and rust, repainted it with Rustoleum, and put down new caulk roll bedding like the original (from Amazon). I screwed in the panels from underneath through the existing screw holes (instead of from the top), so it has a nice clean and smooth finish on the top. I used stainless steel screws. Then coated the underside of the pvc sheets with spray undercoating, just for looks.

It is much better and stronger than new! And, it will never fail.

When did you take it to the factory? I've read (on another website) the owner took his Aria back to the factory 3 times and it still leaks??

I also took the factory tour in 2021 and they said Thor changed the floor design in late 2020 to fix the wet basement issue. Anyone with a 2021+ Aria have a wet basement?

2021 Aria and yes. Thor sent new floor material. They now use a compost floor. Zero wood.

Get in touch with Thor. Send pictures to the customer service folks. They sent me new floor materials. Not wood but a composite material that will not absorb water.

Did you do the work yourself? If so, any hints on how to do it. My wet basement is only in the first basement compartment located behind the passenger tire on the right side.

I plan to take out the old flooring, clean out all the old caulk, clean the steel, paint it, put down a heavy layer of caulk put down the new flooring and again caulk all joints.

In dealing with Thor, I have not been very successful. After about 5 e-mails and 6 follow up phone calls with leaving messages, still have no response about the flooring. They take a message, say they will check on status and let me know. Nothing happens!

Did you do anything special to the bottom side of the wood? The side facing the roadway.

Not my experience. I never call just went though CS contact on their website. I then get a follow up email from a CS rep and go from there. Every issue I had has been done this way and every issue addressed quickly and to my
Satisfaction. The new flooring is NOT a wood product. Thor sent it
To me under good will. There is another thread that the guy did the same. Flex seal caulking and tape. The tape especially there you
Drill the s ld tapping screws. Make sure you send the screws through the tape and it will seal. The other guy also put mud flaps behind the front wheels. His was also that front passenger compartment.
