This Coroplast base is made from 4mm-thick corrugated plastic and is designed to be used with our Cagetopia grids (14" square) with connectors. This Jumbo size is 27"x84.5" for 2x6-grid cages. It is professionally cut and scored and includes reusable, plastic rivets to secure the corners.

Availability: In Stock

Jumbo Cage Dimensions

  • Interior: 27" x 84.5" = about 16 Square Feet of cage space!
  • Exterior: 30" x 90" when assembled with grids (not included in this item) you will need a table space of about 2.5 feet by 7.5 feet to accommodate this cage.

Coro Height Options

  • 6" walls on all four sides. This is the perfect height for keeping bedding contained, visibility to pigs, good airflow, and safety.
  • 12" long back wall only, three sides are 6". May help keep hay and bedding kickout more contained with active guinea pigs, especially when not using fleece, but generally 6" walls are just fine.

NOTE: High walls all the way around a cage are not recommended for guinea pigs as it blocks too much airflow as well as your visibility.

Coroplast Base Includes

  • 4mm Coroplast bottom in your choice of 16 colors!
    The base is pre-cut and pre-scored with pre-punched holes to secure flaps using snap-in plastic rivets (not tape). Coroplast base is creased and folded for shipping, which creates an indented "crush" line. This does not affect the functionality of the cage and is behind the grid wall when assembled.
  • Rivets for fastening all coroplast flaps

Our Cagetopia-brand Grids have stayed the same over the years as we have many hundreds of thousands of C&C cage owners (DIY and customers) that depend on the original sizes and the best quality grids and connectors.

Supplying your OWN GRIDS?

Or mixing in different grid sources or vendors? No 14" grids are the same anymore. Please review:

  • Many 14" grids are NO LONGER COMPATIBLE
  • Grid Vendors are now ALL DIFFERENT from each other
    Especially on Amazon, but also Bed, Bath & Beyond, Target, etc.
    • DIFFERENT CONNECTORS: gap spacing (space between grids) can be different (standard = 3/8") and that matters.
    • Grid Size: 14" exactly is required -- NOT 12" or anything else
    • Grid Wire Gauge (thickness): Grid vendors adapt their connectors to their wire gauge, which is typically thinner than ours (4mm = 3 pennies), so they won't work well together, if at all -- too tight or too loose.
    • Inner Grid-hole Size (safety-related):
      NO INNER HOLES BIGGER than 1.5" or you risk your guinea pig's head getting stuck and strangling. In a 14" grid, there should be 9 holes by 9 holes -- never less.
  • Using only Zip Ties (no connectors) is NOT RECOMMENDED.
    Some people complain about using the connectors. They are using NON-Cagetopia connectors. Ours work great and are easy to snap in, while being strong and stable.
    • Zip ties alone ARE NOT STRONGER as compared to using Connectors WITH zip ties (not opinion, engineering fact).
    • Many Cagetopia products will NOT be compatible for fit without using the connectors.
    • The fit of the coro inside the grids will be different.

Trying to save a few dollars now on purchasing grids separately could be a frustrating, if not an expensive, decision later.

All these things MATTER on CAGE BUILDING.

If you buy one vendor's grids today and try to mix in a different vendor's grids from Amazon tomorrow, odds are high they may not be compatible with each other or our Cagetopia Grids.

The customer service I got was amazing! I got this base because I had c and c grids from amazon basics from a previous cage but wanted to go up from a 2x4 to a 2x6 and since I live in the middle of nowhere there is no place to buy coro. I love how easy it was to set up, my only thing is is that it is a bit pricey but it is definitely worth it.


Easy set up and great design!

Worth every dime! This is durable and last and fits perfectly within the cubes. Easy to assemble and ships fast. Fairly easy to clean and remove. I used to have to buy a new one every 5-6 mos or so because poos and pee stuck to the bottom. Now I clean twice or three times a week and don't have to buy a new base nearly as frequently. TOTALLY RECCOMEND THIS PRODUCT! Just clean frequently to help it last longer.

Luck, WI

You guys.... are amazing.

You've made my move SO MUCH EASIER on me.

I got this base to make a new C&C for my two boars, and I got my new boar on Friday (Sept. 7th) and then learned that I was going to be moving into a new house MUCH faster than we had initially thought. We're moving in within the next two weeks... so for now, the pigs can stay in separate cages (but properly sized) and then, once we move, we can just start the whole cage... anew! Rather than using shower curtains which are kinda icky after awhile.

So, with the way you guys ship (which is amazing. you're fast.) and are able to talk to your customers, just made me so much happier. Plus, you've made my piggies' lives better! Now, in a couple of weeks, they will be in their new cage in a new house, and they will be able to start anew. Just like my parents and I. I think we're all ready. Especially the piggies... they wanna be together!

Thank you guys. I know that was jumbled, but I hope you can see how you made it all easier. THANK YOU.

Highly recommend!

My piggies love their cage!:) I bought pre-cut coroplast from Sue and bought cubes from target. I put the cage together in less than an hour. It is a 2x6 cage with a divider down the middle (Both my pigs like to be dominant, therefore can't be in the same cage) They popcorn and run laps just for fun! Anyone who owns 1 or more guinea pigs should have a c&c cage!
