What Toilet will Replace My Thetford Part Number 42053? Will the # TH35SE Work at an Angle?

Question:

trying to replace my thetford 42053 torlet in my 2014 winnebago. I see you said the TH35SE Is the correct replacement. Great but mounting instruction say I need 9inch to back wall. Mine is mounted at a 45degree angle with only 8inch on one side. Any hope this will fit

Hello Jeff,

Thanks for the pictures, they are most helpful! Yes, you will be able to install the Thetford Aqua-Magic Style II Part-Timer RV Toilet - Low Profile - Round Bowl - White Ceramic # TH35SE which is Thetford's part number 42053, so it is going to be the same exact toilet. You will most likely need to install the # TH35SE same way at a 45 degree angle.

Getting things all geared up for nice weather? Any big trips planned for the year?

Hey Jeff, how did the fit go with the Thetford Aqua-Magic Style II toilet at that 45-degree angle? It’d be great to know if the clearance worked out with your setup. Your update could make it easier for others working with tight bathroom spaces.
