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?
