Per Piece Tile Pricing

Despite my chronic tile phobia, I have to say, I came into the choices for this bathroom with a super chill attitude. Clé was having a big moving sale so I mulled over a few designs for the floor tile but by the time I decided and went to go buy it, most of them were sold out. No problem. I’m very laid back and casual.

I found another on-sale design that would work, added it my cart and was subsequently shocked by the price. Wait, this was only $2.67 per tile (an apparent steal!), how could it be $256 for this tiny bathroom. Well the tiles I found were 8"x8", not 12"x12". So while it was $2.67/tile, it was also $6/sqft. Do not be fooled by per tile pricing. Ok cool, no problem! Going with the flow. I’m breezy.

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.

Rough-ins/Valves

For the shower trim, I bought this mostly ugly but decidedly ok looking shower set by Pfister, a brand name Andrew simply will not stop making fun of.

It is pretty plain Jane but it has a hand sprayer which I wanted since I plan to use this bathroom to wash the doggy as well. Of course there is always another surprise price increase when buying plumbing fixtures since you need to buy the “rough in” valves for them which is basically what makes them work behind the wall, not just the handles you see. What was listed at $265, is actually $326 once all the items are in the cart with shipping and tax.

Half Bath or Full Bath?

A full bath has a sink, toilet, and shower or tub. Full bathrooms are typically added to the master bedroom or are on another floor beside the main floor. Converting a half bath to a full bath can increase your home’s value by up to 20%.

A half bath only has a sink and toilet. Extra bathrooms are usually found near the front of the home as a place for guests to use the facilities without tromping through your house. Small bathrooms can also be useful in the laundry room, mudroom, or garage/workshop. If you’re working with a small space, consider a three-quarters bath, which is a half bathroom with only a shower.

A half bath should be three to four feet wide, and

A half bath should be three to four feet wide, and six to eight feet long, or around 18 to 30 square feet. According to the National Association of Home Builders, adding a half-bathroom can add 10 percent to your home’s value. The decision to add a full or half bath will come down to a few factors:

  • What is its purpose?
  • Where will it be?

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.

Bathroom Addition Cost Factors

Bathroom Addition Cost Factors

Many variables affect how much your bathroom addition will cost such as:

  • Location – If the new bathroom is near existing plumbing, it will cost less than if you need to bring plumbing, vents, and waste lines to the new bathroom.
  • Size – Will you need to knock out walls to make room for the new bathroom or will it go into an unused walk-in closet? Most bathroom additions are inside the home, meaning you won’t have to build out a foundation or add a roof to it.
  • Scale – Will this be a practical bathroom or a luxe addition to the master bedroom?
  • Age of your home – Will the plumbing or electrical work need to be updated before the addition can proceed?
  • DesignArchitect hourly rates are $100 to $250 per hour to design the bathroom.
  • The unknown – Once you begin opening walls and looking into attics, crawlspaces, or basements, you may find some unexpected problems. There could be mold in the walls or a water leak. You might find evidence of pests or asbestos. It’s a good idea to put some extra money in your budget for the unexpected. If you don’t see anything surprising, you can use the extra money to upgrade one of the aspects of your bathroom addition.

Where to Add Your New Bathroom

Your first roadblock may be that you don’t think y

Your first roadblock may be that you don’t think you have enough space for a new bathroom. If you’re wondering, “where can I add a bathroom,” it may surprise you to learn that you can build a half bath in just 3-by-5 feet of space! With 25 square feet, you can fairly comfortably fit a sink, toilet and shower, and with just a little more space, you can have yourself a full bathroom with a full shower and tub.

Where will you put your new bathroom? As long as you have a little available space, access to sufficient electrical outlets, ventilation and adequate sound insulation, you can sneak a new bathroom almost anywhere in your home. It may feel like you don’t have any available space to spare, but there’s a good chance you just don’t know where to look. Secret extra space is scattered through many homes, in areas such as:

  • Hallways: If your hallway extends all the way to the end of your house, possibly terminating in a window with no rooms on either side, you have the perfect location for a new bathroom.
  • Closets: Do you really need all that closet space? A large walk-in closet can often be converted into a new bathroom with just a few minor adjustments. Do you have any adjoining closets? Knock out the wall between them and you should have just enough room for a half bath.
  • Bedrooms: If you’ve got a large enough master bedroom, you may have a chunk of space you’re not using. Partition off that space for your new bathroom.
  • Existing bathrooms: You may be much better served with two small bathrooms than one huge one. Add the necessary fixtures to each side and cut that bathroom in half!

Extending an existing bathroom

A popular option would be extending an existing bathroom instead of installing a new one somewhere in your home. The benefits of this would be that you get to keep your existing bathroom design as you would only be expanding the size of your previous bathroom. In addition, any modifications or improvements you make already have an existing framework to build off of which means less stress on your wallet. Depending on the size of a change you want to make, this type of installation will run anywhere from $2,000-5,000+ depending on how large you want your bathroom to be.

What Should I Know Before Adding a Bathroom?

What Should I Know Before Adding a Bathroom?

Before you look to add a new bathroom to your home, you should ask yourself, who is this bathroom for? Below are some considerations you should keep in mind when looking to add a bathroom: 

You Need Room

You Need Room

No matter what size home you have, space is always a premium. Installing a new bathroom to an existing space such as a closet, garage, or an otherwise underused part of your home can drastically increase the amount of available space. The drawback to this is that you may need to alter the plumbing to reach your new bathroom, and adding a new bathroom can be quite expensive-ranging, from $4,000-12,000.

Make it Accessible

Making a bathroom more accessible is always positive, and especially for older individuals, navigating stairs can be pretty troublesome. So before you add a bathroom, consider its accessibility and look to make it easily accessible for all household members. The most significant drawback to an accessible bathroom will also be ensuring that the plumbing lines up.

Decide on Height

Before you look to install a bathroom, remember to make your calculations and position your fixtures and accessories accordingly. You want to ensure you have a rough idea of how large your space will be to ensure that everything fits; otherwise, it will be a great hassle to re-do an area due to improper measurements.

Fit Pipes Well

You don’t want your bathroom pipes to use the exterior walls for plumbing and fixtures. When adding a bathroom, you want to ensure your pipes are aligned to accommodate everything in your bathroom layout. If you don’t have plumbing knowledge, a plumber will charge you anywhere from $700-20,000, depending on the complexity of your home and existing plumbing setup.

Consider Your Wiring

Many bathrooms often utilize a single outlet which can violate safety issues and risk overloading the power in your bathroom. Plan and distribute your wires evenly so you can use multiple outlets to power your bathroom. An electrician will charge you roughly $200-1,000, depending on the size of your bathroom.

Get Lighting Right

Proper lighting in your bathroom can make it more enjoyable and safer. Keep heavy traffic areas illuminated. You can utilize traditional lighting or add a dimmer switch for a more subdued environment. Mirror backlighting is popular as it is less intrusive than conventional setups. Lights range from $100-500, depending on style and size.

Ensure Proper Ventilation

Moisture and your bathroom don’t get along, so it’s essential to ensure that your bathroom is properly ventilated. Excess moisture can cause mold and odors, so ensure you have a fan that covers at least 1 CFM per square foot of room area. Installing a new fan with ducts and a roof vent will cost around $350, with higher-end models costing about $800.

Tips to save on your bathroom addition

Now that we have a complete break down of dollars and cents, let’s review ways you can save on a bathroom addition and appeal to buyers with your selections in order to maximize your investment:

  • Place the bathroom strategically. As previously mentioned, the closer a new bathroom is to existing plumbing, the less you’ll have to pay to extend water, sewage, and electrical lines. Building a new bathroom a floor above an existing one or close to the kitchen can reduce costs.
  • Buy a “used” tub and other secondhand fixtures. You might not be able to save on electrical or plumbing labor. However, you can purchase used and fixtures and refurbish them to reduce costs. If you have the time to spare and don’t mind browsing a little for a gem, you can end up with some great deals. The Habitat for Humanity ReStore, Craigslist, and local surplus construction warehouses often have new (or like new) fixtures including tubs, sinks and lighting.This new-with-tags Kohler tub was listed outside Seattle for just $250, while comparable models retail for close to $800. Even buying an older, on-trend cast iron tub for a few hundred dollars and paying the average $460 to refinish it could lead to savings.

  • Opt for luxury wood vinyl. Moisture-friendly luxury vinyl plank can be more affordable than other flooring alternatives, and its popularity is on the rise. According to Remodeling Magazine, the demand for luxury vinyl tile has quadrupled in the past five years, and the interest in vinyl flooring has doubled. These flooring options come in a variety of colors and finishes to cater to any bathroom, and buyers are responding to them with more interest than ever.
  • Go for a tile shower over a bathtub. If you’re torn between a tiled, open shower or a bathtub — go for the shower, advises Anderson. “Bathtubs are not trending right now. Buyers like open little walk-in showers without doors,” she shares.

Is it worth it to add a bathroom?

Adding a new bathroom won’t come cheap, but is the value added at resale enough to make the project worth it?

“I always ask my clients, if you’re going to do an improvement like that, how long are you going to stay in the property?” says Anderson. “If it’s five years or more, it could be worth the investment. But, if you don’t think you’re going to stay in the property one or two years, then really reconsider. You’re not going to receive that return back.”
