How to Mount a Pedestal Sink to the Wall

A wall-mounted pedestal sink is essential, significantly if your bathroom is compressed and you need extra storage.

You can use the space below the pedestal for anything, including storing baskets, step stools, or scales. Besides, mounting a sink to the wall shows off tiled walls and creates a more open space than traditional pedestal sinks.

However, installing the wall-mounted pedestal sink to the wall should be easier. Best Bathroom Pedestal sinks come in two parts- the sink and the pedestal.

The plumbing must be compatible with the pedestal, which is fastened to the floor. At the same time, the sink is mounted to the wall and rests on the stand.

Most of the time, the mounting holes may not align with the existing wall studs. If your wall doesn’t have the pedestal sink studs, you will have to use toggle bolts and a silicone adhesive to mount the sink.

Toggle bolts have wings loaded with spring that expand once fixed into the wall cavity. As the bolts tighten, the wings attach to the back of the wall.

6 Steps to Mount Pedestal Sink to the Wall:

Step 1: Align the Sink

Place the pedestal and lavatory in a position you desire. Level up and align the assembly, then put a mark on the walls’ mounting-hole location and the floor.

Pedestal sinks come with a slim base that supports the sink bowl and covers the plumbing connections that furnish the sink. If you’re using toggle bolts, you need to position the sink tightly against the wall to mark the bowls mounting holes on the wall with a pencil.

If your pedestal needs some anchor bolts to fix it to the floor, you also need to mark the floor anchor’s position at this point. However, some pedestal base does not mount to the floor using bolts, and you will have to use caulking or grout to fasten them.

Step 2: Drill the Holes

Drill the fasteners’ pilot holes in the wall and floor. If you’re drilling through a tile, use a masonry bit and fix the areas to be drilled with tape to ensure the bit is centered. After that, set the faucet, the pop-up assemblies, and the drain on the sink.

When drilling the mounting holes, you will need a power drill and the right size and type of drill bit. The drill size should be large enough to let the winged bolt toggle access the wall cavity when attached.

If the wall is stucco, masonry, or covered with stones or ceramic tiles, make sure you use a masonry bit to drill the holes. The hole size required to mount the pedestal to the floor is determined by the type and size of anchors recommended by the manufacturer.  Remember to refer to the instructions that come with the sink.

Step 3: Sink Preparation

Fix the lavatory to the wall using lag screws or other available fasteners, then attach the trap to the draining system.

It would be best if you placed the bowl on the pedestal first for some pedestal sink, position it near the wall, then attach the waste and supply lines before fixing the bowl to the wall.

If you’re using toggle bolts, install them to the sinks back before setting it to place. Since the bolts need a long length to give the toggles access to the walls inside, fasten the winged toggles onto the bolt only for a few turns.

After positioning the toggle bolts in place, apply several drops of silicone adhesive to the back of the sink. The silicone adhesive ensures additional strength and pedestal sink support.

Step 4: Sink Installation

After securing the bowl, drill several pilot holes on the floor for those bolts that will hold the pedestal to the floor. Typically, the pedestal base has some notches in the fasteners’ base.

Once the pedestal base is aligned with the mounting holes, slide the sink closely to the wall to give the winged toggles access to the mounting holes in the wall.

Check out if the toggled wings open after you’ve inserted them into the wall by pulling the bolt head. If it pulls out of the wall, then you’ll have to tighten the toggle bolts with a screw gun or a screwdriver until the snug.

Ensure you don’t over-tighten the bolts to avoid cracking the porcelain. In case the sink has a rod or a nut that connects it to the pedestal, fasten the device, then join the supply lines and install your pedestal.

Step 5: Check out for any Leaks

You attach the drain and the faucet before setting the sink bowl in place. After everything else is specified, reconnect the water supply and the drain to ensure there are no leaks. Let the water flow for a few seconds to let go of the air and any debris.

Step 6: Miscellaneous

Remove any extra silicone that might have squeezed out from the back of the sink using acetone and a rag, then grout or caulk around the pedestal base to fasten it to the floor.

n case the floor requires anchors, fix them into their respective holes and fasten as directed by the manufacturer. To completely install the sink, secure the plumbing, and apply caulk beads to the joints between the wall and the sink.

Conclusion

If stuck, and do not forget to add a lighting fixture and a new mirror to match your new sink look, always refer to the sink’s installation guidelines.
