"Michael and team did such an amazing job on our bathroom remodel. They took our tiny, dysfunctional bathroom and turned it into a true master bathroom oasis in a short amount of time during the holiday season. When they had the space down to the studs, Michael sat down with us and discussed in detail the best possible use of the space and we couldn’t be happier with our final decision after going through the options. Michael was great at communicating and we still stay in touch to this day, which we truly appreciate. Great team who does great work and I will absolutely be giving Waters Construction a call for any and all future home renovations. I’ll let the pictures do the rest of the talking. "

Interior Design and Decorating questions, answered by experts

The typical cost of an interior designer is around $8,000, but you might spend as low as $200 or as much as $65,000, depending on the size of your home, the services you want, and the quality of the decor. Your price for interior decoration will always increase with home size, as more square footage requires more materials and labor. Your price will also be higher if you want your decorator to choose and purchase materials in addition to arranging them in your home. Higher quality furniture and decor will also drive up your cost.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

There are a few ways to cut down on your overall project costs for an interior designer if you want to update your home on a budget. Some ways to reduce costs include:

  • Purchasing your own products, which can save significant money on commission costs for your designer. 

  • Design one room at a time versus your whole home, to stick to a current budget. 

  • Only paying for a consultation, which will give you expert tips for DIY design. 

Longer curtains can visually extend the height of a space, especially if they are hung on a rod that sits above the window frame. Place the rod up to 20 inches above the windows to open up a space. And while sill-length curtains are still common, many homeowners today prefer the floor-length look for a more open and airy vibe.

Ideally, a pot filler should not be centered but rather installed to the left or right of the cooking surface to avoid having to reach over the hot area to access it. If this arrangement isn't possible, you can technically center a pot filler above the cooking surface, but you'll need to take care not to burn yourself. Also, the filler itself will become hot from a large boiling pot or stovetop.
