How to Remodel a Bathroom from the Ground Up

Step 1: Demolition

If you missed the beginning of the series, here’s how the bathroom looked when the guys arrived.

The guys completely gutted the bathroom, removing

The guys completely gutted the bathroom, removing the vanity, toilet, tub, shower walls and floor. They removed all the fixtures like towel bars, soap trays, medicine cabinet and more. The only thing they didn’t remove was a portion of the drywall.

Can you add a bathroom anywhere in your house?

The short answer is yes, you can install a bathroom almost anywhere that you can afford it. However, this will largely depend on your plumbing and electrical setup and what style of bathroom you want, which goes into another common question.


Step 6: Concrete Board

Steve hung Durock concrete board on the shower walls using OSI adhesive and 1-1/4″ concrete board screws. Concrete board is moisture and mold resistant, it doesn’t deteriorate in the presence of water, and concrete board is the preferred underlayment for tile.

The Cost to Add Another Bathroom

Many people don’t even consider adding a bathroom because they are sure bathroom remodeling is too expensive. Finding the space and building it out, along with adding plumbing, makes the cost to add a bathroom seem prohibitively expensive. It doesn’t have to be. The key is to find the right approach so the benefit of an extra bathroom outweighs the cost. Remember, adding a bathroom can significantly increase your home’s value, so with the right approach to bathroom remodeling, the ROI can be strongly in your favor.

How much does it actually cost to add a bathroom to your house? Not considering the cost you’ll recoup, the upfront investment can run anywhere from $3,000 if you already have a space in your home to install the bathroom to $25,000 if you have to add on to the footprint of your home.

You can easily spend more than this if you’re looking to install a large, luxurious bathroom, or you can save if you work with your existing layout and opt for simple fixtures, so make sure you get a quote that takes your project specifications into account.

Does adding a bathroom to a house increase taxes? The answer depends on a few factors. If your project requires a permit, then a tax assessor may notice the additional value you’re adding to your home. If you add on to the square footage of your house, you can definitely expect an increase in taxes. Even if you end up paying a little bit more in taxes, the added value to your home will far outweigh this small expense.

How Long Does a Bathroom Renovation Take?

The time it takes to complete your bathroom reno depends on how extensive the job is. A cosmetic renovation of an existing bathroom can be completed pretty quickly. A more comprehensive renovation typically takes around four and a half to nine weeks. If you add on to the footprint of your home to add a bathroom, then you can expect the job to take quite a bit longer.

Common questions about adding a bathroom

Is there existing water and waste piping near your new bathroom?

Before installing, check to make sure that water flow exists for your new bathroom. If it doesn’t, you may need to hire a professional plumber to sort out your needs and get water flow to the room of your choice.

Do you have enough space for a bathroom?

An important question to consider, as not every space can fit all the bathroom necessities you may require. The starting point for most bathrooms is roughly 25 square feet-this size gives you just enough room for a small bathtub, a toilet and a sink, though keep in mind this size may be too small for you.

Does your city code allow you to add a bathroom in your designated space?

Another tricky subject as every city will be different and it is important for you to consult your nearest authority on the matter. Many cities do not permit alterations to your home or some extensions may be too large for city code without the right permits, so it is best to understand what you can and cannot do to your house before you begin.

Should you have a professional assist with adding a bathroom?

The short answer is yes. In many cases, electrical and plumbing alterations must be handled by a trained professional. If you are confident of your abilities and have the requisite experience, then some steps can be DIY, but ultimately, utilities must be handled by a professional.

Adding a bathroom to your home can help to increase the value of your home, but it would be best to consult a professional to assess your situation to prevent any unnecessary building mishaps that may occur and further costs as well.  

How to Plan for a Bathroom Renovation

Decide on Design Elements

Before you start remodeling the bathroom, choose a design that fits your vision, as well as your DIY skill set. There are many different ways to approach this project, ranging from repainting and swapping out the vanity to gutting the space and starting from scratch.

Here are a few details you absolutely need to nail down before you begin your bathroom renovation:

  • Color scheme: Interested in a modern farmhouse look? Or are you looking for a clean, contemporary design to match the rest of your home decor? Find inspiration photos for your vision ahead of time to make sure your new bathroom tiles don’t clash with your choice of paint.
  • New fixtures: Will you replace your shower or tub? Are you installing a new sink? Replacing one or both of these fixtures will add to your project’s timeline and budget.
  • Storage spaces: Where will you keep your towels and toiletries post-remodel? If you’re removing a closet to expand the room, make sure you have shelving or cabinets to make up for the lost storage space in your bathroom.
  • Location of utilities: Do you know where the electrical wiring and plumbing pipes are located? Keep these areas marked to avoid damaging these hookups and having to make expensive repairs.
