Ready to refresh a compact RV vanity? A Bathroom Sink in a Single Sink layout keeps the footprint simple while giving you plenty of bowl space. Expect lightweight plastic options and drop-in installs; plan on silicone sealant, and some drains glue instead of thread. Check overall measurements, bowl depth, flange width, and faucet hole layout, since cutouts and mounting tabs may need slight trimming for a snug fit.
Pre-position the mounting tabs and screws before dropping the sink in, since access can be cramped. If the sink sits proud, check underside tabs—trimming or notching has helped in some installs. If screws bottom out, try shorter ones. Dry-fit, mark, and then seal to reduce rework in tight spaces.
Measure your existing cutout and the sink's overall size, then compare flange widths. Some installs needed minor trimming or notching of mounting holes, and a few people cut tabs to sit flush. Cutout templates may not be included, so plan to use the sink itself as a template and dry-fit first.
Silicone sealant is commonly used under the rim and to caulk the edges. If the drain tailpiece doesn't thread on, ABS/PVC cement has been needed to glue the drain connection. One installer used double-sided tape to help hold position before caulking. Always test-fit the plumbing before final bonding.
It can, but check hole count and spacing if you want to reuse your faucet; some were able to do this, others modified openings. For drains, some tailpieces glue on instead of threading, and an adapter to a 1-1/2" trap may not be included. Verify your trap size and whether you'll need a separate adapter.
