If you are in the market to buy a home and plan on looking at a lot of different properties for sale then you need to make sure that you are as prepared. You can't go into the home buying process not knowing what you want out of a home for sale or you will be wasting a lot of time. It doesn't work that way. You need to know what you want your new home to have so you can tailor your house hunting experience to meet your criteria.
If that means you want to live in a house with a really big backyard, then only go to showings of houses with really big backyards. If you need to live in a house that features custom glass railings and doors (much like the examples found here) design and build, that you can show off and brag about; then make sure to tell your real estate agent that. Eliminating potential homes off your list will save you a lot of time, as you won't be going to home showings of properties you know you won't be buying. That time can be better used to carefully inspect other homes you might actually consider buying.
If you're the type of person who wants a very accessible bathroom or needs their privacy when using the bathroom then you might want to consider only properties that have ensuite bathrooms. Ensuite bathrooms provide you with the solitude you need when using the bathroom. You don't have to worry about someone wanting to use the bathroom or barge in unannounced because they don't have access to it. Most ensuite bathrooms are usually bathrooms inside the master bedroom so you don't really have to walk far to access them.
If that's something you are looking for then make sure to tell your real estate agent about it so he can set up showings only with ensuites. If for some reason you just can't find a home that has one of their features then you can always get an architect to come up with some blueprints for one and then hire a contractor to come in and build it for you or to renovate the master bedroom to include an ensuite bathroom.
Ensuite bathrooms are nice luxury to have but in some households, one full of children or visitors or tenants, having an ensuite bathroom is a necessity.
