A groin vault is formed by two barrel vaults intersecting at right angles. The result is four curving surfaces that draw the eye up and toward the center. The areas where the barrel vaults come together create ribs that add both strength and visual appeal.

Easy to Install
Easy to Install

Your groin vault will come with simple instructions making installation a breeze.


  1. Measure the long side of your groin vault to the nearest 1/8”. 
  2. Measure the short side of your groin ceiling to the nearest 1/8”. 
  3. Choose a rise for your groin ceiling kit to the nearest 1/8”. 
  4. Enter the location (place) where the groin ceiling will be installed in your project (for example: Dining Rm, Gallery Hall, Entry, #1 Groin Ceiling).


Every groin ceiling kit comes with tailored installation instructions to your specifications. It's as simple as measuring and marking the placement of each strut, nailing each strut in its place, and then adding back bracing with an occasional cripple. If you can color by number and operate a nail gun, then you can install one of our groin vaults.  



Drywalling a groin vault is comprised of measuring the curvature, cutting the drywall to the curvature, forming and fastening in place.


  • Wetting the back of the drywall (as shown in the video) will make the drywall easier to bend.
  • For a tighter radius, consider using a double layer of either ¼” or ¼” flex drywall.


How long does it take to get my groin vault ceiling?

Groin vaults normally take 10 - 14 business days to manufacture (in most cases sooner). Then add a few days for shipping. Plan for 2 1/2 to a little over 3 weeks from date of order.

How do you ship my groin vault?

Depending upon the size of your groin vault and/or the size of your total order, it will either ship in boxes via UPS Ground or in a crate via UPS Freight. Normally groin vaults less than 8 feet will ship UPS Ground, and anything larger will ship UPS Freight. Once your order has finished processing (usually 1 business day after order), you'll be notified when and how it will ship. If you’d like to know before you order, call us and we’ll let you know.

How do you finish groin vaults?

Drywall, plaster, wood veneer, brick veneer, trim, tile… the list is seemingly endless. Whether you want your groin vault to have a simple or an ornate finish, the choice is yours. You can also watch our "7 Creative Ideas to Finish Your Ceilings & Archways" YouTube video.

what our customers are saying

We’re a fan of the groin vault kits from Archways & Ceilings. We have been using them for a few years now and the quality and the ‘WOW’ factor their groin vault kits create are well worth the cost. Plus, their customer service is excellent!

We were absolutely satisfied with our dome ceiling. The service and communication we got from Archways & Ceiling was top notch. We would highly recommend working with them and using their products.

I would highly recommend Archways & Ceilings for coved ceilings. Their kits takes what can be a hard task for a carpenter and makes it into a simple project. The savings over other products we have used like Styrofoam is significant with better durability.

Archways & Ceilings does a great job on all of their products. Specifically, we have been using their barrel vaults exclusively since 2009 and the exact precision with which they are made cannot be replicated in the field by traditional stick framing methods. For a truly high-end finish and a shape nothing short of perfection, Archways & Ceilings materials are the way to go.

Archways & Ceilings is a great company to have as a resource.  We know that when we take on projects that require a variety of arched ceilings, we can count on them to come through.  We recently completed a project that required an elliptical barrel vault that intersected with 6 half circle arches at different heights which they call “Igloos.”  This ceiling came out terrific and came out like the architect spec’d.
