Yes, there seems to be one on every cabin deck, but not in the same place, just ask your room attendant after you board. There are also irons and ironing boards in those rooms too.

The Conquest has coin operated self serve laundrys with free use of iron and ironing boards. Laundry rooms are located in front of rooms 1359,2367,6387,7339,8351 and9270
I believe it costs $3 to wash and $2.50 to dry if I remember correctly. If you don't want to pay high prices for laundry supplies, bring your own ie: dryer sheets and laundry soap tablets.
We used the laundry room a few times. As I remember, the washer costs $1.50 and the dryer costs $2 (for 30 minutes, but for many items, you will need more time). The soap costs 75 cents for those small boxes good for one wash. I did not bother to bring soap, but you may want to take a small bottle or powder.
On our deck 7 laundry room (near room 7339), there were four or five washers and three dryers plus a sink. The room had one ironing board and one iron. The iron plug was attached to a timer, so this would certainly prevent anyone from leaving the iron on hot for too long.
The ironing room does get busy on the dressy nights (Monday and Thursday) when many passengers want to iron their clothes.
On Thursday, a SMALL laundry bag was placed in each cabin. On Friday morning, if any guest wanted to fill this bag with dirty clothes, the clothes were washed, folded and returned later on Friday for a price of $12. I did not think very many clothes would fit into the bag.
In a balcony room, the small table when covered wth a pillow case and towel could make a good ironing board.
