Furthermore, the sink is mounted to the wall and rests on the stand.

In fact, if your walls doesn’t have the pedestal sink studs, then in that case, you don’t have many options but 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.

Beginner’s Friendly Steps to Mount a Pedestal Sink to the Wall

So, here I come with beginner’s friendly steps to mount a pedestal sink to the wall.

All the below-mentioned steps are quick, easy, and less time consuming.

Align the Sink

First thing first, you need to place the pedestal and lavatory in a position with which you’re comfortable.

Level up and align the assembly, then put a mark on the wall’s mounting-hole location as well as the floor.

I’m assuming that most of you would be aware of the fact that pedestal sinks come with a slim base that supports the sink bowl as well as covers the plumbing connections that furnish the sink.

Furthermore, if you’re using toggle bolts, you need to CAREFULLY position the sink tightly against the wall in order to mark the bowls mouting holes on the walls with the help of a pencil.

However, if that isn’t the case, and 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.

But, at the same time, you must be aware of the fact that all the pedestal base doesn’t mount to the floor using bolts.

And, by chance you’re facing any such problem then you’ll have to use caulking or grout to fasten them.

Drill the Holes

Once you’re done with the aforementioned steps, the next thing that you need to do is to drill the fasteners’ pilot holes in both floor and wall.

Well, if you’re drilling through a tile, then in that case, you might have to use a masonry bit and fix the areas to be drilled with tape to ensure that the bit is centered.

The next thing that needs to be done is the setting of faucet, the pop-up assemblies, and most importantly, the drain on the sink.

Moreover, the prerequisite of drilling mounting holes are a power drill and the right size & type of drill bit.

Make sure the drill size is large enough to let the winged bolt toggle access the wall cavity when attached.

You’re not left with much options but to use a masonry bit to drill the holes in case the wall is stucco, masonry, or even covered with stones or ceramic tiles.

On top of it, the type and size of the anchors recommended by the manufacturer will decide the size of the hole required to mount the pedestal to the floor.

It’s always advisable to refer to the instructions that comes with your pedestal sink, isn’t it?

Sink Preparation

Either with the help of lag screws or other available fasteners you can easily fix the lavatory to the wall.

Afterwards, you need to attach the trap to the draining system.

For the best practice, place the bowl on the pedestal, position it near wall, and then attach the waste and supply lines before fixing the bowl to the wall.

On the other hand, if you’re using toggle bolts then to make things simpler and easier you need to install them to the back of the sink before setting the latter to its 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.

Now, its time to apply appropriate amount of silicone adhesive to the back of the sink post positioning the toggle bolts in place.

The good thing about silicone adhesive is that it ensures additional strength and pedestal sink support.

Sink Installation

Once you’ve secured the bowl, the next thing that needs to be done is to drill several pilot holes on the floor of your bathroom for those bolts that will hold pedestal firmly to the floor.

Typically, the pedestal base has some notches in the fasteners’ base.

Once you’re done with aligning pedestal base with the mounting holes, the next thing that needs to be done is sliding the sink closely to the wall to give the wingled toggles access to the mounting holes in the wall.

Make sure the toggled wings get opened after you’ve inserted them into the wall, and you can check this by pulling the bolt head.

In case, it pulls out of the wall, then you’ve to correct this discrepancy by tightening the toggle bolts with a screw gun or a screwdriver until the snug.

While doing so, you must make sure that you don’t over tighten the bolts in order to avoid cracking the porcelain.

Furthermore, if your sink has a nut or a rod that connects it to the pedestal, then make sure you fasten the device and then only join the supply lines and finally, install your pedestal.

Check for Leakage

Make sure you attach the drain and the faucet before setting the sink bowl in place in order to avoid any unprecedented event or last-minute misadventure.

Once rest of the things are specified, all you need to do is to reconnect the water supply and the drain in order to ensure there are no leaks.

Allow the water to flow for few seconds in order to let go of the air and any debris if present.

Final Step

Last but not least, remove any extra silicone if present from the back of the sink.

You can do it by using acetone and a rag.

The next thing that needs to be done is to grout or caulk around the pedestal base to fasten it to the floor.

Well, in case, your floor requires the anchors the fix them into their respective holes and fasten as directed by the manufacturer.

In order to completely install the sink, make sure the plumbing is secured and caulk beeds are applied to the joints between the wall & the sink.
