We are going to replace our dishwasher with an integrated dishwasher. This also includes installing a dishwasher door. Additionally, we will replace the vanity unit in the bathroom but keep the sink. For that installation, some silicone against the wall and the sink will need to be removed and reapplied.
For both the kitchen and bathroom renovations, water and such installations are already in place. In the bathroom, the necessary holes are already drilled as it's a matter of replacing the vanity with one of the same model (same dimensions and screw holes, etc.).
Can one do this oneself without experience, or should help be arranged?
