Your Homyze Guide On How To Repair Or Install Bathroom Drywall

Bathroom drywall (or partition wall to some, stud or sheet wall to others) installation isn’t the easiest of tasks, but with the required patience, money and know-how, you too can have your bathroom back to looking its best.

So whether it’s the result of a repeatedly swinging door that has now left an uncomfortable looking doorknob dent, or you have an unmissable hole left over from a DIY disaster, our helpful step-by-step HOMYZE guide on how to repair or install bathroom drywall will teach you all you need to know about this DIY task.

Before you start your Bathroom Drywall

After checking you have all the relevant tools and materials to hand (more on which you can read below) the first step of installing a bathroom drywall is ensuring that the work area is prepared and ready for the drywall repair or installation.

Clear the room of any household items and place protective sheets down in any areas that may be affected by the work.

When you start your bathroom drywall repairs or installation always make sure to measure the area. As all experienced tradespeople say … “measure twice, cut once”.

Ensure all light switches, light fixtures, pipes and any other fittings are also noted, as these will require being pre-cut into the drywall beforehand.

Before you get down to the hard work, make sure you’re wearing the appropriate protective clothing. Goggles, dusk mask and padded gloves might not be this season’s style, but they are all essential for avoiding any unnecessary injuries when undertaking drywall work. Any hospital visits have been excluded from the prices and process below.

You will also need to consider the fact that your bathroom is an absolute hotbed for moisture in your home and you’ll need to use a drywall designed specifically to resist moisture build up. Most trade shops stock specific moisture resistant drywall, and while it may be more expensive than standard drywall, it will help save you from moisture and mould in the future.

Repairing a Bathroom Partition Wall

When it comes to repairing your bathroom drywall it’s always best to consider how much work is actually required. A single, small dent is obviously going to take up less of your precious time and hard earned money than multiple, unsightly holes.

Repairing a Dent or Small Hole

For the more straightforward of jobs, such as a small dent or hole, simply removing any surrounding debris and filling in the affected area with filler is the best way to go. Once dry, simply sand down the rough area until smooth.

Repairing a Large Hole

Unfortunately, repairing larger holes in drywall isn’t as straightforward as repairing small holes and dents (surprise!), and requires a fair bit more time and work.

1) Preparing the drywall

First things first, cut the replacement drywall to a size roughly two inches larger in height and width than the damaged area. Place the newly cut drywall over the damaged area and trace around it with a pencil. Carefully cut away at the newly marked area with a drywall knife, however, before this, ensure that the area in which you are cutting is free from any electrical wires. You can buy detectors that can provide you with the position of things such as cabling, screws or supports.

2) Out with the old, in with the new

Now that the damaged area has been removed, place thin wooden strips, commonly known as furring strips, on both sides of the inside of your newly cut hole. Insert a screw through the wall and into each end of both of the furring strips to hold them in place. Place the previously cut drywall over your hole and drill into the furring strips to help hold them in position.

3) Fix the edges

Once the drywall is firmly in place, apply joint tape along the cut borders to ensure it remains secure and helps to prevent any future cracking. Go over the area with a joint compound, making sure that it is well covered before leaving to dry.

4) Smooth the area down

Roughly 24 hours after originally applying the joint compound, sand down the area to a smooth finish with a drywall sander. However, for those on a budget and without access to a drywall sander, sandpaper (well, really you!) can do just as good a job, as long you aren’t afraid of a bit of extra hard work.

Cost of repairing a bathroom drywall


As with pretty much every type of DIY job around the home, when it comes to the cost of repairing a bathroom drywall, the answer is always “it depends”. It mostly depends on the extent of the damage and/or how much of it there is to replace.

But in addition to this variable, you’ll need to account for your tools. If this isn’t your first time when it comes to carrying out DIY around the home you may already have the required tools to hand. If not, you’ll need to splash out on the following:

  • Drill
  • Drywall sander
  • Drywall knife
  • Utility knife
  • Tape measure
  • Protective clothing

While the knives and tape measure combined shouldn’t cost you much more than £10, the sander and drill will. Available in all shapes and sizes, a decent drill can set you back anything from £40 to a £100+. It’s always worth considering how much use you’ll get out of your drill when evaluating the alternatives. Simply going for the cheapest option might end up costing you more when you get down to the actual work.

Much like the drill, a decent drywall sander can cost you a fair amount, and if not being regularly used, is probably not worth it. Sandpaper can make a decent and cheap alternative, and as long as you don’t mind the added work, it can save you a decent amount of money.

Protective clothing may often seem like a bit of an afterthought when you’ve considered all the other tools, but it can often be the most important. You’ll ideally want to have protective gloves, goggles and a dust mask. All in all these items should cost around £20. We understand that you may not be wearing a bespoke suit to do your drywall job, but when compared with the cost of your health or a nasty accident, protective clothing is a necessity, not a luxury.


It’s all well and good having the right tools and equipment, but without the necessary materials, you aren’t going to get very far. To carry out a bathroom drywall repair, you’ll need:

  • Replacement drywall
  • Furring strips
  • Joint tape
  • Joint compound (or filler)
  • Screws

Altogether, these materials should cost you around £20-£30, but that all really depends on how much drywall you require to cover the affected area(s).

Installing a bathroom drywall

An example of newly installed drywall - how to repair or install bathroom drywallA far trickier task than simply repairing bathroom drywall, installing drywall is guaranteed to take up more of your time and to test your patience (not to mention the overall cost of the job).


However, the effort is often worth it, as a transformed bathroom can bring new life into any home – let’s just hope it doesn’t increase your water and heating bills with people spending longer in the shower!

1) Measuring up

To begin, much like when repairing drywall, you will need to measure up the area before cutting your drywall to fit your space.

2) Start at the top

Top sheet of drywall installed - how to repair or install bathroom drywallThe ceiling is always the best place to start. Ideally, you’ll have someone on hand to help you guide the drywall into place, but if not, a drywall lift will help in making sure the drywall remains aligned and perpendicular with the rafters. Once in place, insert a screw through the drywall and into the rafters, keeping a distance of about 12 inches between each one. Make sure to start inserting the screws from the centre of the boards and work your way out as this will guarantee the partition (or stud) wall holds nice and flat to the rafters.

For an extra few points from the judges (a Homyze Pro move), once you have lined the first sheet of drywall up with the ceiling, put a screw in to hold the sheet in place. It’s a lot easier than trying to hold it flush against the wall supports.

3) Move down to the walls

Screwing down drywall - how to repair or install bathroom drywallOnce your ceiling drywall is firmly in place, it’s time to move on to the walls. Again, you’ll need a drywall lift or someone on hand to help hold the drywall in place as you hold it tight to the frame. Work from the ceiling down and avoiding any fixtures for the time being, insert the screws through the drywall and into the frame, placing one every 16 inches or so.


4) Filling in the gaps

Drywall around bathroom fittings - how to repair or install bathroom drywallWhen fitting drywall in your bathroom there are bound to be various gaps and fittings that you will need to work around. Any areas left over can easily be covered simply by scoring down the drywall before snapping it away and cutting along the paper at the back of the board. Don’t worry about any rough edges as these can easily be smoothed down.

A gap along the floor is also to be expected, as two sheets will often come just short of the ground. This can easily be resolved simply by adding skirting at a later date.

Fittings, such as an electrical box, can be a bit trickier, but by measuring up the problem area and then marking it up on the drywall, you should be able to resolve these little challenges.

Remember to take into consideration the distance of any adjacent panels, before cutting away with a drywall knife to ensure a smooth fit.

5) Applying the joint compound

Filling between drywall - how to repair or install bathroom drywallOnce all the drywall has been fitted, you’ll want to go over all the joints, both vertical and horizontal, with joint compound followed by tape which should be then pressed down into the compound with a knife. Roughly 24 hours later the joint compound should be dry and another layer of the compound should be added to ensure the surface is smooth and any tape is firmly covered.

6) Smoothing the surfaces

Sanding the drywall after installation - how to repair or install bathroom drywallAfter waiting 24 hours, the second layer of joint compound should be dry and you can get to work on sanding down any excess compound or rough edges.

Just a note of caution … be careful about overdoing it on the sanding as this may result in the drywall tearing.


7) Repeat

Repeating step of drywall installation - how to repair or install bathroom drywallYes, it might be starting to get tiresome, but applying a further layer of joint compound should be done, before waiting another 24 hours and sanding down as necessary. This will guarantee any missed rough edges can be picked up and smoothed.

8) Done and dusted

Drywall after installation - how to repair or install bathroom drywallGive the room a quick rub down with a damp sponge to help remove any unwanted dust, before leaving your work to dry.

Your new bathroom drywalls are now ready to be finished with your material or colour of choice.

Whether you want to put some new marble tiles, or just opting for a freshly painted finish, all the time and effort you put in preparing your walls for this moment will be worthwhile. It might take a bit longer to do it right the first time, but it pays off many times over as you continue through the job. If you think it is difficult to get a straight and smooth finish on your drywall, try and tiling on top if it’s not!

Cost of installing a bathroom partition wall

Breaking down the costs of installing bathroom drywall can be tricky as every home’s bathroom is different in size and shape. As we usually say, “it depends”.

Tools for Installing Sheet Wall

Having the correct tools is perhaps the most expensive part of undertaking any job yourself, and a key reason (as well as the labour itself) that people hire a professional tradesman. However, if you plan on getting the job done yourself, and done properly, you will need the following:

  • Drill
  • Drywall lift
  • Sander
  • Drywall knife
  • Utility knife
  • Tape measure
  • Protective clothing

All together it’s a fair amount, and you could easily be looking at over a £100 in tools for what could be a single job.


For materials, you should expect to be spending around another £100 but this can vary depending on the size of your room. To completely install a new sheet wall bathroom within your home, you will need the following:

  • Replacement drywall
  • Furring strips
  • Drywall tape
  • Joint compound
  • Screws

Not counting the replacement drywall, altogether these materials shouldn’t be costing any more than £70 – £100, depending on how much joint compound you get through. For reference,  moisture resistant sheet wall for bathrooms will usually cost around £8 per square meter.
