Since everyone has different wants, needs, and budgets, figuring the cost of your bathroom isn’t as easy as looking at an estimate. The average is a good starting point, but planning your bathroom out takes a little more work than that. 

There are many things to consider when determining the cost of a new bathroom. After all, this isn’t a living room or bedroom. Bathrooms involve plumbing, toilets, sinks, which can add up.  

Standard Bathroom Appliances

The first thing to consider are standard appliances. A half bathroom needs two appliances, a 3/4 bathroom needs three, while a full bathroom can have more.

Let’s break down the prices so you can see what each item will cost:

  • Shower – $300 to $10,000
  • Bathtub – $250 to $25,000
  • Sink – $50 to $3,000
  • Toilet – $100 to $2,000

Anything aside from these four things would be extra. Amenities are things you don’t need in your bathroom, and are considered extras. 

Bathroom Size

The size of your bathroom reconstruction project is directly related to how much it will cost. For bigger bathroom projects, you can expect to pay more than you would for small restoration projects. However, a preexisting space would also be cheaper.

The size of the bathroom affects the cost. It won’t affect the cost as much as the quality of your appliances, but will vary depending on the square footage. Some bathrooms are as small as 20 square feet, while others are larger than master bedrooms.

Most bathrooms are 40 square feet. This is usually a 5×8 bathroom. The size is big enough to hold a small tub, sink, and toilet. The tub often is a shower/tub unit designed to save space while offering both options. 

Bathroom Plumbing

When building a new bathroom or adding space in your bathroom, there a few things to consider regarding your plumbing system, like the main drain line for example.

The plumbing system in your bathroom space should be handled by a professional. Anything can and will happen. This is why it’s important to search online for the best bathroom renovation contractors near you.  After you choose one, sit down with them and map out a plumbing strategy.

The average cost to hire a plumber is around $100 an hour, with the range being around $50 to $200. Though the amount of time needed to do your bathroom can vary greatly too. It is best to get a binding estimate beforehand. 

Plumbing Issues

We understand there’s no such thing as a perfect job, especially when installing new plumbing or adjusting existing plumbing.. After your bathroom addition is complete, you may experience plumbing issues.

Why Does My Bathroom Smell Like Rotten Eggs?

After a your bathroom renovation is complete, you may notice a foul and pungent odor coming from your bathroom after you take a shower. Usually, the odor smells rotten eggs.

If you’re experiencing this problem, then the smell is hydrogen sulfide. To resolve this issue, you’ll need to install a new p-trap.

What Is A P-Trap?

A p-trap is a device that’s shaped like a horseshoe. The trap functions as a waste pipe, connecting a drain to a home septic tank or city sewage system. A p-trap will always contain a little bit of water.

Basically, a p-trap prevents noxious gases like hydrogen sulfide or methane from entering your home. If a p-trap isn’t cleaned or replaced, debris can accumulate and clog the drain. 

Another issue is how p-traps can vent sewer gases into your living spaces. This is caused when the water in the trap evaporates over and isn’t around to trap expanding gases. If you’re experiencing this problem, don’t worry, it can be fixed easily. All you have to do is run water through your other drains that are seldom used.

Adding On Vs Remodeling

Building a new bathroom will always be the most expensive option. However, there are two different ways to add a bathroom. The cost of a bathroom depends on whether you are adding on or remodeling an old bathroom. If you are remodeling an old one, it will be significantly less.

When remodeling an existing space, it’s cheaper because plumbing, electricity, and walls are already in place. Your electrical costs will be lower because you won’t have as much to install, for example. 

But if you are adding on, you get to start from scratch without taking up any space that is in your house. 

If Cost Isn’t An Issue
