Materials & Care

Materials: The Williamsburg window box includes a stainless steel planting box with an antique copper finish and thick iron mounting brackets with a black powder-coated protective finish.

Antique copper finish process: The planter is electroplated with a copper finish, then hand-rubbed to create an antique look, and sealed with a high-grade clear-coat protective sealer.

Optional annual protection: You may apply a clear spray sealant once per year (inside and outside) for added protection—some customers also apply it before first use.
  • Avoid constant overflow: Minerals/chlorine/soil additives can contribute to spotting if water runs down the exterior.
  • Not designed as a fountain: Continuous water exposure is not recommended.
  • Winter storage: Optional. Clean with mild soap + water, dry thoroughly, then store if preferred.
  • Mounting note: Brackets are not designed for metal railings. For railing mounting, explore HoldItMate® systems.
Product FAQs

Does this 30" Williamsburg window box include brackets and hardware?

Yes. This window box includes 2 mounting brackets and standard hardware. If installing on masonry or other surfaces, you may need alternative fasteners.

Does the Williamsburg window box have drainage holes?

Yes—drainage holes are included to help prevent waterlogged soil and support healthy roots.

Is stainless steel suitable for outdoor planting?

Yes. Stainless steel naturally resists rust and corrosion and is commonly used for durable outdoor applications.

Will the antique copper finish change over time?

The finish is sealed, but natural aging can occur depending on climate, watering habits, and exposure—many customers enjoy the character it develops.

Is this Williamsburg style available in other sizes?

Yes—shop Williamsburg 36" and Williamsburg 48" for wider spans and more planting room.

Can I mount this to a metal railing?

The included brackets are not designed for metal railing installation. For railing-mounted setups, we recommend exploring HoldItMate® systems.

Keeps my coffee as hot as I want it to be
Color: Silver
This coffee warmer is much better than the candle warmer that I was using for my coffee before. With a range of 3 temperatures, I have a choice of temperatures from hot to very, very hot, and the warmer shuts itself off after a while, just in case I forget. The description advises that ceramic cups do not retain heat as well as flat-bottomed cups, but I have not found that to be a problem. Coffee in my ceramic mug stays as hot as I want it to be. The knob on the side makes this warmer easy to turn on and to select a temperature, plus I feel that it is a good value.

Perfect Mug Warmer
Color: Black
I bought this to replace one I'd had for more than 25 years & I'm glad I got this one. Keeps my hot drinks hot for hours & will shut off after that. Quickly heats back up when needed. Very sleek looking. Easy to set up. Just take it out of the box & plug it in.

I love it for my workspace! Hot tea all day
Color: Wood Grain
I love this item. The size is perfect, as I prefer something less bulky for my work desktop. It isn't as fancy as others that has the digital display screen, which is fine by me, because I don't necessarily need that. The knob and different colors that indicate the temperature range works fine. The temperature on this thing works fantastically well for me. Using it on the lowest setting keeps my drink nice and hot in a cold office. I use a heatproof glass teapot with this and its a good fit. It keeps my tea hot throughout the day, so I am able to pour smaller amounts of drink and take my time sipping it throughout the day without worrying that it will get cold. At point I almost forgot that it has an automatic shut-off safety feature when I noticed it was off. So that is a good feature to have. I highly recommend this.

Requires a very specific mug to be useful.
Color: Black
The hotplate itself gets hot enough on its highest setting where it would burn your finger if you left it one there for more then a couple seconds. However when it come to what mug you can use to transfer that heat to your drink, this WILL NOT work with just any old ceramic, metal or glass mugs. You absolutely need to have a perfectly flat bottom on it. If the center of the bottom of the mug does not make direct contact with the very center of the warmer, it will not transfer heat. So straight way plan of spending another $15 to $20. Amazon has some available with good reviews all be it not a very big selection. I'm giving this 4 stars because the description needs to be very clear about this and its not.

Great mug warmer with temp control
Color: Black
I replaced a cheap mug warmer with a couple of these for the house, and for almost the same price this is a lot more functional. I really like the temperature control and silicone surface protector. In combination with the carafe below, this has changed my life - no more microwaving coffee all morning. https://www.amazon.com/GiNT-Stainless-Thermal-Thermos-Retention/dp/B07MW5N7MS
