22-1/2 inch deep 10 inch wide 6-1/2 inch high chamber used over 20 years it reading approximately 60 degrees off at high temperatures (1900-2000 degree range), rather than rebuild with new controls and elements I will be using a professional service outside. the cost of rebuilding this will run upwards of$800. a new Evenheat KF-22.5 is $1400 to $1800 before freight to Alaska.Kiln has a brand new thermocouple installed and some slotted firebrick to hold projects. this kiln still throws 2000 degrees plus heat and maintains within 10 degrees so it is probably great for glass slumping or ceramics as is. if no answer on phone send a text
