Very Victorian. In true Victorian fashion, lavish details unfold all throughout this master bathroom, including on the floor-to-ceiling carved fireplace surround, which marries perfectly with the adjacent freestanding undermount tub.

Tip: Place furniture around the fireplace for a posh pre- or postbath lounge area. A good book and a fluffy robe would turn this spot into paradise.

Old-world charm. The stacked stone and exposed wood ceiling transport this bathroom to another time and place. A rustic chandelier and simple tub complete the old-world feel.

Tip: The fireplace ledge here is also a functional place for a glass of wine, candles or bathing supplies.

Timeless traditional. Symmetrically separating his-and-her vanities, this fireplace stands front and center. Traditional white painted wood allows the design to stay timeless for years to come.

Tip: For total design cohesion, make the mantel the same material as the countertops.

Cool and contemporary. A sleek stainless steel fireplace at tub level allows you to enjoy the view without craning your neck during a long soak.

Tip: Make sure to allow for plenty of room to walk between the tub and the fireplace. Many fireplaces become very hot.

Inside-outside connection. Bring the outside right indoors with a desert fire of your very own. This is earth, wind and fire working in complete unison.

Tip: When purchasing a gas fireplace, look for the option to have glass or stones set inside the fireplace for an accent — stone would look beautiful here.

Designer. Skylights accentuate an all-white marble fireplace in this designer master bathroom, which seems to have everything.

Tip: Paint the firebox with white heat-resistant paint so it blends into the wall, almost disappearing until you hit the ignition.

Clean and classic. The simple lines say classic, and the crisp color says clean. This classic fireplace flows with the style of the beautiful vanities. I love that the fireplace uses real wood too; the smell helps create an extra-cozy vibe.

Tip: Place coordinating sconces above the fireplace for added ambience.

Grand slam. Everything in this bathroom has grand proportions — even the extra-large fireplace with a huge mantel. The fireplace sits in front of a two-person tub, while walls of vanities peak out from behind. This bathroom has just about everything you'd need for a spa-style afternoon.

Tip: Go above and beyond by adding a remote control to the fireplace so you can turn it on and off while in the tub.
