Are you tired of looking at your old, outdated tile? Thinking of ditching the tub in favour of a modern, walk-in shower? You'll have to remove the current bathroom and install the new one. For those who want to hire a professional to oversee the rest of the renovation, demolition dumpster rental on their own and using a dumpster rental are simple ways to cut costs. 

This work is physically demanding but requires no specialized skills. It's a simple job that the average homeowner can do with just a few items from around the house.

Bathroom Demolition—The Method

Removing the Door

First, ensure that the door is shut and latched before continuing with this task. After that, remove the hinge pins by hitting the underside of each pin with a nail to loosen it. Use your fingers to draw them out of the hole when they have risen about an inch or two. If they don't budge, use a screwdriver with a flat blade to pry up on the knuckle's underside.

Taping the Vents

Essentials You'll Have to Have on Hand

  • Mastic (a water-based duct sealer)
  • Aluminum Window Screen
  • Putty Knife 
  • Aluminum Tape
  • Tools like a screwdriver, scissors, paper towels, and rubber or nitrile gloves will also come in handy.

The vent cover should be unscrewed and set aside. You can get rid of the dust that has settled inside the metal duct by wiping it down with a moist rag.

To use aluminium tape, you'll need to rip it into long enough strips to wrap around all four sides. There should be two shorter and two longer sections.

It's important to peel off the tape's backing slowly and carefully. You only have one chance to aim, so make it count!

Ensure the tape sticks to the first few inches of the metal duct and extends about a quarter of an inch down onto the floor. Put some serious pressure on it, and it will stay put. Do the same on the opposite side, completely sealing the seams between the tape.

Sealing Tape

Even while the tape performs excellent sealing, it may become loose as the metal expands and contracts with the seasons. A duct sealer is necessary for this purpose.

Use a putty knife to spread a thick layer of duct sealer on the aluminium tape. Be sure the sealer meets the floor, but don't get any on the tape. Avoid turning onto the tape placed directly on the ground as you ascend.

Make sure there are no globs of sealer on the floor, and clean up any mess you caused before waiting for the sealer to dry. Go to the next vent on your floor and do the same thing there.

Removing the Toilet

A toilet may be more difficult to remove than other fixtures in your bathroom, but it is still possible to do so. Before doing anything else, turn off the water and remove the cistern from the toilet. 

At times, glue and silicon sealant stick toilet bowls to the floor. If that's the case, pry the toilet bowl with the bar. You can easily remove the bathroom equipment from the wall and lift it off the floor.

Getting Rid of the Vanity

After removing the old hardware, it's time to focus on the sink and vanity. To access the drain lines, unscrew the P-trap that connects the sink to the plumbing. Unscrew the sink from the wall brackets and disconnect the water lines (if any). Using the pry bar, you can pry your sink loose if it is stuck.

You can easily remove your bathroom vanity by unscrewing its cabinet from the wall (if it has one). If your vanity is similarly screwed on too tightly, you can use your pry bar to remove it.

Removing the Tiles

You will need the following tools and materials:

  • A sledgehammer or mallet
  • Chisel for masonry
  • Heavy-duty scraper for the floor
  • a pry bar
  • Putty blade
  • Use a shop vac, broom and dustpan to remove dust
  • flat shovel and wheelbarrow to remove dust and debris.

You may need other materials and tools, depending on how the floor looks after the tiles. Don't forget about safety equipment. When you take tiles off a concrete floor, there is a lot of dust and debris in the air, and you may need to use harsh chemicals. 

Wear a respirator mask that fits well, eye protection, a long-sleeved shirt, and work gloves to keep from getting hurt or breathing in dust. Also, because you'll be kneeling on a hard surface a lot, invest in a pair of kneepads.

Understand the Type of Tile You're Removing

If you are taking up linoleum or vinyl tiles that were put down before 1980, make sure they don't have asbestos. Asbestos was once mixed into vinyl floor tiles to improve insulation and fire resistance. Asbestos may be present in the glue used to adhere to these tiles.

The asbestos tile should only be taken off by a trained professional because it can be hazardous to your health if it gets broken up. You may keep the tiles in place and cover them with concrete.

Ceramic Tile Removal from Concrete

Find a good place to start when removing ceramic tiles to quickly get the masonry chisel under the tile. It's best to see or feel a cracked or loose tile. Areas with deteriorating grout are also good starting points.

Work the masonry chisel under the tile at a 45-degree angle, so you don't gouge the concrete floor. Take a few good whacks with a mallet on a chisel until you can loosen and pry off the tiles. 

If you come across a stubborn tile that won't budge, smash it into pieces using a sledgehammer.

Removing Vinyl Tile From Concrete

Removing vinyl tile or linoleum flooring requires a different approach because the tiles are pliable and will not crack like ceramic tiles. Here's how:

With a putty knife, pry up one corner of one of the vinyl tiles. You may have to use a utility knife to cut through the tile if there isn't a loose corner.

Next, slide a floor scraper or a putty knife underneath the tile and lift it completely off. If the tiles are hard to move, heat them with a hair dryer or heat gun. This will soften the glue and make them easier to scrape up.

How to Remove Tile Adhesive

Once you've removed all the tiles from a concrete floor, your work is far from done. You will also have to remove any underlayment or backer board under the tiles. But the job would often be challenging if the tile was put down directly on the concrete without an underlayment.

Most of the time, tiles are stuck to concrete subfloors with either adhesive mastic or thinset mortar. The removal method you use will vary depending on the material.

If removing mastic, scrape it with a broad chisel or long-handled floor scraper. If that doesn't work, try softening the mastic with hot water (most tile adhesives dissolve in water) or a commercial mastic remover made just for getting old adhesive off concrete floors. 

When the mastic starts to dissolve, return to it with the scraper. (Learn more about removing glue from a concrete floor.)

Unlike mastic, thinset hardens into a cement-like substance that you can't remove by dissolving. You have to chip away at it repeatedly with a chisel, a floor scraper, or a rotary hammer with a thin-set removal bit. Wear a face mask and goggles when removing the thin set, regardless of the method.

When to Use a Concrete Grinder

If scraping and mastic removers don't get the job done, you can grind off any leftover thin-set or mastic with a concrete grinder and then use an angle grinder to work with tiles along the walls and in corners. 

Most of the time, grinding is the best way to get a smooth surface and get concrete ready for a decorative finish.

Because concrete grinding equipment is expensive, consider renting one from a home improvement store. To make cleanup easier, use a grinder that has a port for connecting a dust vacuum, allowing you to collect the grinding dust as you work.

If you've never used a concrete grinder before, consider hiring a professional contractor who will know which grinding discs to use and how to operate the machine without damaging the concrete surface.

Removing the cement boards and shower tiles

In this approach, taking off individual tiles is unnecessary.

First, cover the ceiling, windows, doors, and walls or floors with plastic sheeting. Sheets should overlap by 3 inches before taping them into place. Cover any fixed furniture or fixtures with the sheets and secure them with tape.

The second step is to remove the registers from the walls and floors and then tape plastic over the opening. You have to remove the outlet cover screws and cover the hole with masking tape.

Put on some long pants and a long-sleeved shirt. Don't forget to wear safety goggles, leather work gloves, and a respirator mask with two cartridges.

Press a thin chisel the same size as the grout lines or slightly smaller into the grout. It would be best to pound the chisel until it shatters the tile. Once you reach the cement backer board beneath the tiles, tilt the chisel to a 60-degree angle. Keep chipping away at the grout with the chisel until the joint is clear.

Remove the entire seam between the walls by holding the tool at the right angle and tapping to remove grout from corners where an angle chisel won't work.

Fix the tile joints by replacing the cracked grout. Move it off the floor and onto the tiles.

Position a reciprocating saw at a right angle to the grout line you just cut. Get close to the middle of a nearby wall or floor. The cement-backer board must be slowly cut through. The blade should still be in the cement backer board as you bring the saw down to almost touch the ground or the wall. To get to the end of the board, you'll need to keep sawing through it.

Put a pry bar through the opening and beneath the board, then remove it. Tear it all up, tiles and everything, from the ground or the wall. To tighten screws, provide additional force. Raise the eliminated plank and place it somewhere out of the way.

Remove the tape from the ceiling first, peel the plastic sheeting back, and lay it flat on the floor. Keep the dust and dirt contained when you remove the plastic by rolling it up before you start unrolling. Discard the sheeting by placing it in a garbage bag.
