Hey Romy,
The Seaflo Toilet # SE25MR is not considered a direct replacement for your Sealand 210. The rough in measurement and flange size overall are different from your current model. The Seaflo is smaller at a 8-1/2" rough in and 4" flange diameter. For your toilet we do have a direct replacement that I recommend from Dometic # DOM29FR. This is going to be the same measurements as your current toilet and install the same.
What kind of trailer do you have this in?

Hey Romy, did the Dometic toilet work as a replacement for your Sealand 210? I'm curious because it might help others with the same setup.
