3. Setup and Installation
Important: Installation should be performed by a qualified professional or an experienced individual. Ensure all local plumbing and building codes are followed. Two people are recommended for safe installation.
3.1. Before You Begin
- Inspect all components for damage before installation. Do not proceed with installation if any parts are damaged.
- Ensure you have all necessary tools: measuring tape, level, drill, stud finder, screwdriver, wrench, sealant, and appropriate wall anchors/screws for your wall type.
- Turn off the main water supply to the installation area.
- Clear the installation area of any obstructions.
3.2. Mounting the Vanity
- Locate Wall Studs: Use a stud finder to locate and mark the positions of wall studs where the vanity will be mounted. This is crucial for secure installation.
- Mark Mounting Height: Determine the desired height for your floating vanity. Mark the top edge of the vanity on the wall, ensuring it is level.
- Mark Mounting Points: Based on the vanity's mounting bracket locations (refer to included assembly instructions), mark the drill points on the wall.
- Drill Pilot Holes: Drill pilot holes at the marked points. Ensure the drill bit size is appropriate for your chosen wall anchors or screws.
- Install Mounting Hardware: Secure the mounting brackets or ledger board (if applicable) to the wall using appropriate fasteners. Ensure they are firmly attached and level.
- Mount the Vanity: With assistance, carefully lift the vanity and align its mounting points with the installed wall hardware. Secure the vanity to the wall according to the assembly instructions. Double-check that the vanity is level and securely fastened.
3.3. Plumbing Connections
- Install Faucet: Install your chosen faucet onto the sink according to the faucet manufacturer's instructions.
- Connect Drain Assembly: Install the drain assembly into the sink. Apply plumber's putty or silicone sealant as required to ensure a watertight seal.
- Connect Water Supply Lines: Connect the hot and cold water supply lines from your wall to the faucet. Hand-tighten, then use a wrench for a final quarter-turn, being careful not to overtighten.
- Connect P-Trap: Connect the P-trap to the drain assembly and to the wall drain pipe. Ensure all connections are tight to prevent leaks.
- Test for Leaks: Slowly turn on the main water supply. Check all plumbing connections for leaks. Tighten any leaking connections as needed.

5. Maintenance and Care
Proper care will ensure the longevity and appearance of your Weibath vanity.
5.1. Cleaning the Sintered Stone Countertop
- For daily cleaning, wipe the surface with a soft cloth dampened with warm water and a mild, non-abrasive cleaner.
- Immediately wipe up spills to prevent potential staining, although sintered stone is highly stain-resistant.
- Avoid using harsh chemicals, abrasive cleaners, scouring pads, or acidic substances (e.g., lemon juice, vinegar) as these can damage the surface finish.
- Do not place hot items directly on the countertop without protection.
5.2. Cleaning the Engineered Wood Cabinet
- Wipe the cabinet surfaces with a soft, damp cloth. Dry immediately with a clean, soft cloth to prevent water spots or damage.
- Avoid excessive moisture. Do not use abrasive cleaners or solvents.
- Periodically check and tighten any loose hardware (handles, hinges) to maintain stability.
5.3. Cleaning the Ceramic Sink
- Clean the ceramic sink with a mild, non-abrasive bathroom cleaner and a soft sponge or cloth.
- Rinse thoroughly with water after cleaning.
- Avoid harsh chemicals or abrasive materials that could scratch the ceramic glaze.

6. Troubleshooting
This section addresses common issues you might encounter with your vanity.
6.1. Leaks from Plumbing Connections
- Issue: Water dripping from pipes or connections under the sink.
- Solution: Turn off the water supply. Carefully check all connections (faucet, drain, P-trap, supply lines). Tighten any loose connections. If a connection continues to leak, it may require new plumber's tape or sealant.
6.2. Drawers or Doors Not Closing Properly
- Issue: Drawers stick or do not close smoothly; cabinet doors are misaligned.
- Solution: Check for obstructions inside the drawers or cabinets. Ensure the vanity is level. Adjust drawer slides or door hinges if necessary (refer to specific hardware adjustment instructions if provided with the vanity or hardware).
6.3. Surface Stains on Countertop
- Issue: Despite being stain-resistant, some stubborn stains may appear.
- Solution: For persistent stains, use a specialized cleaner recommended for sintered stone surfaces. Always test the cleaner on an inconspicuous area first. Avoid abrasive scrubbing.
