I own have a four bedroom house which is perfect upstairs. However, the downstairs is badly configured. I would like to make downstairs open plan and I am considering getting rid of the downstairs toilet to do so. I have two bathrooms upstairs, one is an en-suite. My question is, would this devalue the property? My husband thinks we need a downstairs toilet but I don't think it's necessary. Currently the downstairs toilet has no window and is right next to the lounge which is very off putting for visitors anyway.
