If you own a house that has fewer bathrooms than bedrooms, then it’s not a good thing for the people living in the house. The bathroom is place that is used frequently, you can’t just wait outside and wait for your turn. If you are thinking about the adding a new bathroom, that’s a great thing to do. The addition of a new bathroom will not only make your home more comfortable, but it will also increase the value of your home. 

That’s right. Although adding a new bathroom in your house is not cheap, it can increase the rate of your house by at least 30 percent when you look to sell it. The location of your house also matters for its value. Different studies show that when you add a new bathroom, it increases the value of your home up to 30 percent and has the strongest impact on your home features. This is mainly due to the optimisation of living space in your home. The worth of the home also depends on the number of bathrooms and rooms you have in your house along with many other factors. 

The National Association of Homebuilders

The National Association of Homebuilders reported that if you add a half bath, it will increase the value of your home up to 10 percent. A full bathroom will increase almost 20 percent of the value of your home. If you have more bedrooms in your house than the bathrooms, then adding a new bathroom will increase its value significantly. According to the study, if you have one bathroom in a two-bedroom home, adding a half bath will increase the value of your home by an average of 11.5 percent. If you have three bedrooms in the home, an addition of half a bath will increase the value by 12 percent and for a four-bedroom home, it will increase by 12.5 percent. Adding a full bathroom will increase the value even more. Adding a master bathroom in your home can raise the value to 30 percent.

The National Association of Homebuilders Model

The National Association of Homebuilders has developed a model to estimate the worth of a new bathroom for a house. It is developed by using statistical techniques to form data that were updated in several years by the American Housing Survey. In 2005, the American Housing Survey released data and according to their model, a half bath adds almost 10 percent, and a full bathroom adds almost 20 percent value of a house. According to the American Housing Survey, the full bathroom that comprises a bathtub or shower, flush toilet, a sink, cold, and hot piped water can double the value of a house – a half bath consisting of only cold and hot piped water and toilet. 

The model of the National Association of Homebuilders is bendable, it affects the value of the home in different forms. Along with the half and full bathrooms in a house, the number of bedrooms and bathrooms has a powerful impact on the value of a house. This model suggested the buyers of houses choose a rough balance between the bathrooms and the bedrooms because the addition of a bathroom will increase the value of a home by a higher percentage. The addition of a half bath in a standard single-family house that is in a 1700 square-foot having two bedrooms can increase the value of the house from $180,710 to $201,576 on average. The addition of two full bathrooms can increase its value from $221,854 to $224,786 on average as per this model.

Opendoor

According to Opendoor, you can increase the value of the median home by 5.7 percent with the addition of a full bathroom. You can add a bathroom in as little as 30 square-foot of space in your home. You can use the basement area, under a staircase, and a repurposed laundry room for a new bathroom. If you are thinking about adding an upscale bathroom, it would be the best idea. It will increase your home’s value by a decent amount of money also

In the 21st century, no one wants to live in a house having three or four bedrooms with a sole bathroom. Adding a new bathroom in your house not only gives you benefits when you are living there but also helps in making the house more marketable.

In a nutshell, the addition of a bathroom will increase almost 10 percent of your house’s value. If you convert a half bath into a full bathroom, it will increase by approximately 9 percent of the house’s value. So, the addition of a bathroom in your house can increase almost 19 percent of the house’s value.
