Enhance your living space with this piece of vintage décor that compliments both traditional and modern styles. The 36" Sebastian fireplace mantel is a pre-cast fabrication that parallels the look of extravagant marble or granite interpretations. Fine cut stone appearance adorns the generous hearth stone and matching crown molding style header and mantel shelf. Two graceful columns (legs) embrace the hearth and truly accent the entire piece. The Sebastian brings a classic architectural motif to any room with its beautiful definition. 

Want to know the secret to the perfect look we achieve with these pre-cast mantels? We simply take a mold that has been made from a wood model and pour a lightweight gypsum and fiberglass reinforced concrete mixture into it. The result is sturdy products with crisp, clean lines.

These gypsum products have a natural white finish and are shipped unprimed. Once you receive your vintage-style mantel, you can customize it with your choice of paint or other faux finish to match your décor. Please remember that CJ's Hearth & Home loves getting pictures from our satisfied customers once their mantels projects are complete!

IMPORTANT: The 36" Sebastian mantel arrives unassembled in 5 pieces (hearthstone, two legs, header, and mantel shelf). It is heavy and will require a couple of people to set up. This is a project that will take you a few hours to install. Allow at least 48 hours for the construction materials (thin set, adhesive, and grout) to dry, and an additional 2-3 weeks for materials to fully cure before you attempt to paint your Sebastian fireplace mantel. Please watch our very informative and easy to understand video on the right side of this page!

**Please note** Items in the photo (George Washington painting, fireplace, fireplace door) are not included with this product. The 36" Sebastian fireplace mantel includes the hearth stone, two legs, header, and mantel shelf ONLY.


  • Made of pre-cast stone - a gypsum and fiberglass reinforced concrete that comes in a natural white finish. Can easily be painted or faux finished.

Features and Benefits

  • Cast stone mantels save you money over hand carved from granite or marble options.
  • Because we use lightweight gypsum and fiberglass reinforced concrete in our pouring methods, our mantels are lighter than regular concrete, granite, or marble.
  • Cast stone mantels come unassembled and primed for painting, allowing you to customize your mantel to fit the décor of your home perfectly!
  • Mantel comes with the hearth (the bottom slab in front of the fireplace) and matches the mantel shelf!

Customer Service
I must say the ladies in customer service really do go above and beyond. They have been quick to respond and extremely helpful. I can not wait to get my concrete bowls and install them. Thank you Dana and Lindsey for great service.

I left feedback ONLY yesterday and see that it has been removed. I guess this company has no explanation as to how they determine pricing and shipping cost. I see that others have left negative feedback and CJ Hearth & Home had chosen to respond. In this case, CJ Hearth chose not to respond to my pricing inquiries and their returns policy.

Fire pit has small flame
When I put my fire pit glass on top of the orafice, it seems like the glass is covering the hole/ports and the fire is very sporadic which is limiting the heat from the pit. Any suggestions on what I can do?
