Wendy Davison, 50, died at home in Derby last month after a 10-year battle with cervical cancer.
Russell Davison, who has been left "heartbroken", said he did not want her body to go to a mortuary and he wanted to challenge attitudes towards dying.
It is legal to keep a body at home and Derbyshire Coroner's Court confirmed Mrs Davison's GP reported her death.
Mr Davison said: "Death seems to be such a taboo subject in our society, no-one seems to want to talk about it.
"I did not want her in the mortuary or handed over to a funeral director, I wanted us to take care of her ourselves at our family home, have her in our bedroom so I could sleep in the same room."
When Mrs Davison was diagnosed shortly after the couple's joint 40th birthday party in 2006, they decided to take a "natural" approach to her healthcare.
"We were not prepared to hand her life over to doctors. We wanted to do our own research and do the very best job we could to keep Wendy alive," he said.
He believes their approach, which included refusing chemotherapy and radiotherapy, extended Wendy's life "by a very long time".
'Beautiful and comforting'
In 2014, Mrs Davison was given six months to live, so the pair went travelling across Europe, where they had "the absolute time of our lives".
But last September, they were forced to return home when her pain became too bad.
She received hospice care at the Royal Derby Hospital but they were determined she would not die there.
The pair decided she would be cared for at home by family and her body would remain there until her cremation.
She died on 21 April.
"Wendy died very peacefully, fully sedated, in no pain, in mine and Dylan's arms with our ever faithful dog Elvis snuggled up right next to her too," Mr Davison said.
He said it was a "beautiful and comforting experience" to have family and friends over to see her during that time.
