Don’t overlook the little details

“The best bathroom design embraces minimalism and warm halogen lights and decor items that reflect the environment around them,” says Dobbels. “We want guests to have that jaw-dropping moment when they venture into the bathroom—every single detail matters and conveys a sense of place.”

Think about the aspects that you appreciate most about staying in a hotel and try to emulate them in your own space. Is it the sense of minimalism? The lighting? The amenities? Those small details are going to play a much bigger role than any renovation you could do.


Issues to Consider When Installing a Bathroom Yourself

If you are designing or installing your own new bathroom, there are a few points you will want to keep in mind. First, the bathroom must have ventilation. When choosing your space, try to find one with a window already built-in. If you can’t, you will need to put in a duct fan or a new window of some kind.

Make sure your floor can handle the weight of your new bathroom, as bathroom fixtures can weigh up to 20 pounds per square foot. Find out what kind of capacity your floor joists are equipped to handle.

Do the math. The main reason to do bathroom remodeling yourself rather than call a professional is economic. Between the tools, equipment and supplies you will need to purchase and the amount of time you need to dedicate to the project, you might not actually save that much money. It can be a good idea to get a professional estimate first before even considering taking on bathroom remodeling on your own.

Costs are another factor to consider. While a bathroom can be added very affordable by taking into consideration your current bathroom situation, the average cost to add a bathroom in 2019 is around $7,600. This can be as low as $2,500 if updating an existing space and keeping the upgrades simple, or as high as $25,000 if adding an entire addition onto your home to make room for the new bathroom. Regardless, there are ways to cut costs while still building your dream bathroom. Ask your plumber or contractor about the most cost-effective ways to incorporate your new bathroom.

Consider adding a bidet attachment

Bidet seats, particularly those that are easy to use are a fantastic option when trying to make a bathroom more welcoming. “Many of the bidet seat additions come heated, so even if the guest does not want to use the bidet functions, the seat still provides extra comfort,” explains Daniel Johnson, founder of ManyBidets. “Installation takes about 15 minutes, and simply replaces the existing toilet seat—so it’s really a breeze to set up.”

Running Copper Supply Lines

With drain and vent lines all set, it's time to try your hand at running copper supply lines. Check your local codes to see what type of material is recommended, though copper is preferred in most. In this step, you will be cutting, installing, and sweating pipes, so make sure you are comfortable doing so before beginning. We will walk you through all the necessary steps and offer solutions to common plumbing problems.

8. Factor in storage

Storage is the key to a successful bathroom – and no, a minimal glass shelf won’t be enough! Toiletries never display well (unless you’ve taken out shares in Aesop or Jo Malone), nor do shampoo bottles standing on the floor of the shower. A substantial vanity with space for extra towels is a smart buy, plus any kind of storage unit too. Here the homeowner has transformed two simple bookcases into bathroom storage to hide away their toiletries.

‘Mirrored cabinets will allow for you to store products, as well as charge toothbrushes and electric razors,’ advises Chris. ‘Niche storage in the walls will also ensure that you can store bottles discreetly when in the shower.’

‘The least thought about part of any bathroom is often storage – finding solutions to bathroom storage can often be tricky but with some careful consideration, there’s actually a multitude of options for storing your products, advises Fabrizio Costingo, Product Designer at Lusso Stone (opens in new tab). ‘A vanity unit doubles up as a practical storage cabinet, whilst also creating a statement in the room. Or, if your area is long and narrow, a wide set of cabinets that can sit against a wall could be a good use of space, again, doubling up as both storage and a ‘getting ready’ station too.’

31. Pare Down Your Bottles

Let’s be honest: We usually don’t need all those toiletry bottles. Streamlining your grooming products will give you more space, so do a Marie Kondo and pare down your shampoo collection. Or, at the very least, store the products you don’t use daily somewhere other than your counters or bathtub ledges. Getting rid of any clutter will make your small bathroom seem much bigger.

12. Finalise a budget

Deciding on a budget in advance means you can prioritise where to spend and where to save. And the good news is that it doesn’t have to cost thousands to create a spa feel. Invest in just one beautiful piece, such as a freestanding bath (which you can pick up for under £500) and show it off against a more budget-conscious backdrop.

‘Set yourself a budget and be realistic. It is easy to overspend, so make sure you consider all aspects of bathroom design, from plumbing and electrical work, to tiling and decorating. Budget is also important if you plan on selling your house in the future. Afterall, you want to ensure you don’t invest more than you are likely to recoup,’ advises Faye

Bear in mind you also need to allocate some money to practical elements. You might need a larger water tank if you are planning a rainfall shower, and a water softener can be a smart idea to prevent the build-up of limescale.

Bathroom Addition Cost

The average cost to add a bathroom addition to an existing space is $7,600 with some homeowners paying as little as $2,500. The cost to build a new bathroom addition to your house will cost around $22,000 on average, or $47,000 to $87,000 on the high-end.

Average Cost To Add A Bathroom
National Average Cost $7,600
Minimum Cost $2,500
Maximum Cost $25,000
Average Range $4,500 to $12,400

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.

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?

2. Switch Out Decor

When guests come over, I try to make the bathroom a little more personality-neutral so I switch the shower curtain out to a nice hotel-worthy fabric, I change out the artwork, and I add plants and candles to make it feel welcoming.

I never buy these items, I just shop my house for decor I can use and replace them after guests leave. Noah’s existing bathroom decor goes in a bin in a storage closet so I can put it back up later.

Plumbing Tips for Adding a Bathroom

When you’re adding a new bathroom, consider these tips to help make your project a success:

  • Know what you want your new bathroom to look like before you start. Check out Pinterest photos and home improvement sites online for ideas.
  • Place fixtures strategically. If you can place your new fixtures close to existing water and waste lines, you can keep construction costs and plumbing bills down.
  • If you’re installing a door in your new bathroom, install one that swings out or a sliding door. This will maximize the available space for fixtures and make it easier for guests to navigate inside your new bathroom.
  • Keep an eye out for products that will make the process easier, either because they are more affordable, easy to install or both. For example, the Qwik Jon® Ultima Sewage System by Zoeller is designed so you can put a toilet just about anywhere, which is perfect for your new bathroom project. However, adding a toilet to an existing bathroom in an old house will be a huge cost saver as it will drastically cut installation time.

Brighten Up Space

The bright and clean bathrooms feel relaxing, welcoming, and can make even small spaces feel larger.

How to Brighten Your Bathroom without Windows

Adding greenery with faux plants can help brightenIf your bathroom is like mine and doesn’t have any windows, try painting it a lighter color. I’d also recommend removing large dark pieces of furniture and using open shelves to help free up space on the walls.

Adding greenery with faux plants can help brighten your space and bring more color to the room!

Make Your Space Brighter with Windows

If your bathroom does have windows, let the light shine in! But, make sure to add shades or a privacy film to the windows.

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.

Provide Grooming Essentials

After I’ve stocked the towels, I make sure that my bathroom is stocked with basic grooming essentials. That way, I know they have what they need, in case they’ve forgotten something at home. For these essentials, I will store them on our open shelves, on the counter, or I will show then where they are stored in the vanity.

  • Shampoo/Conditioner (can be travel sized)
  • Bath soap
  • Lotion
  • Toothpaste
  • Extra Toilet paper
  • Face wash
  • Mini first aid kit
  • Misc. Toiletries (razor, nail clippers, tampons, etc.)
  • Bathrobe
