No problem that makes a lot more sense as almost all fuller size stand-up fridges have the icemaker option. These kits can be added to most brands for $75-$99 here is a Frigidaire 15 top freezer around 28 wide 60 tall. Does take the icemaker will cost less in white. Don’t get scared of by the manufacturers list price there is always a deal to be had on these. https://www.frigidaire.com/Kitchen-Appliances/Refrigerators/Top-Freezer-Refrigerator/FFHT1425VV/
